Circuit building block time. The capacitance multiplier and how it gives almost negligible power supply ripple compared to a voltage regulator. Whiteboard theory and then some bench demonstrations and experiments. Plus a twist at the end that proves that the "Capacitance multiplier" is perhaps one of the most mis-named circuits of all time.

Ultralow Noise and Ultrahigh PSRR
 
05:57
Amit Patel - Senior Design Engineer, Power Products When it comes to powering noise-sensitive analog/RF applications, low dropout (LDO) linear regulators are generally preferred over their switching counterparts. Low noise LDOs power a wide range of analog/RF designs, including frequency synthesizers (PLLs/VCOs), RF mixers and modulators, high speed and high resolution data converters (ADCs and DACs) and precision sensors. Nevertheless, these applications have reached capabilities and sensitivities that are testing the limits of conventional low noise LDOs. For instance, in many high end VCOs, power supply noise directly affects the VCO output phase noise (jitter). Moreover, to meet overall system efficiency requirements, the LDO usually post-regulates the output of a relatively noisy switching converter, so the high frequency power supply rejection ratio (PSRR) performance of the LDO becomes paramount. With its ultralow output noise and ultrahigh PSRR performance, the (http://www.linear.com/product/LT3042) LT3042 can directly power some of most noise-sensitive applications while post-regulating the output of a switching converter, without requiring bulky filtering.

Troubleshooting Eurorack Noise Issues
 
14:36
After thinking I was going to lose my mind due to, um, noise issues, I replaced the switching power supply (Volgen KTPs65-1543DT 3P) on an Enclave case (MakeNoise Powered Bus Board) with a linear power supply (Triad WDU 15-1700) and that fixed almost all of the issues. The situation could be further improved by putting oscillators and VCAs on their own bus board. This video is a bit dry and not very linear. Skip to 11:30 for the before/after punchline. Thanks to Paul T Schreiber for suggesting a linear power supply and to Mr. Nelson of Trogotronic for pointing out that one of my power supplies was linear after a lengthy email exchange about diagnostics. To apply this to your situation, you need to know three things, all of which should be on the label for the power supply: 1. The input voltage and frequency. In other words, your wall power A/C is. In the US that's 120V at 60Hz. 2. The output of your existing power supply. e.g. 15V at 1.7 A 3. The polarity of the output. With those parameters you can search for a power supply. In the US Mouser and Newark have great interfaces for finding power supplies. You can identify linear power supplies because they only accept a single voltage/frequency combination. In addition, it's typical to see a capacitor at the end of the circuit which helps to smooth the converted current. In my case I went with this one rather than a more powerful one specifically because the output circuit was very simple, with a typical bridge rectifier followed by a capacitor: http://catalog.triadmagnetics.com/Asset/WDU15-1700.pdf

Simulation Of Adjustable Bipolar Voltage Regulator Circuit Using LM337-CIRCUIT WIZARD SOFTWARE
 
10:02
Simulation Of Adjustable Bipolar Voltage Regulator Circuit Using LM337-CIRCUIT WIZARD SOFTWARE Design and Description of Project : For op-amp circuits the power supply must provide positive and negative voltages. Here is a simple circuit “Adjustable Bipolar Voltage Regulator” which gives regulated ± 1.2V to ±2oV supply. ICs LM317K (IC1) and LM337K (IC2) are used here as positive and negative regulators respectively. The IC1 LM337 has internal feedback regulation and current passing elements. It incorporates various protection circuits such as current limit (which limits package power dissipation to 15 watts for the TO-220 package and 20 watts for TO-3 package) and thermal shutdown. Thus these two ICs form an independently adjustable bipolar power supply. The steel K package will easily furnish one ampere each if the heatsink are properly mounted. Variable resistor VR1 and VR2 are adjusted for each regulator to give a regulated output approximately between ±1.2V to ±20 volts. Capacitors C5 and C6 are used to improve AC ripple voltage rejection. However, if a short-circuit occurs across the regulator output, C5 will adjust the current in the terminal. The output of adjustable bipolar voltage regulator can be calculated by the formula. V0 = 1.25V(1+VR1/R1) Comoponents : R1, R2 = 120Ω, 0.5W VR1, VR2 = 2 KΩ LIN C1, C2 = 4700 µF/25V (Electrolytic Capacitors C3, C4 = 0.1 µF (Ceramic Capacitors) C5, C6 = 10 µF/35V (Electrolytic Capacitors) C7, C8 = 1 µF/35V (Electrolytic Capacitors) IC1 = LM317K IC2 = LM337K D1 – D4 = 1N5421 X1 = 230V AC primary to 22V-0-22V, 1.5A Secondary Transformer

Minimizing Switching Regulator Residue in Linear Regulator Outputs
 
05:00
with Jim Williams http://video.linear.com/75?utm_source=minswreg&utm_medium=video&utm_campaign=youtube Linear regulators are commonly employed to post-regulate switching regulator outputs. Benefits include improved stability, accuracy, transient response and lowered output impedance. Ideally, these performance gains would be accompanied by markedly reduced switching regulator generated ripple and spikes. In practice, all linear regulators encounter some difficulty with ripple and spikes, particularly as frequency rises. This video, excerpted from LTC Application Note 101 (http://cds.linear.com/docs/en/application-note/an101f.pdf), explains the causes of linear regulators' dynamic limitations and presents board level techniques for measuring and improving ripple and spike rejection.

Use the Cleverscope Frequency Response Analyser to measure the Power Supply Rejection Ratio (PSRR) of a power supply with the CS1070 Power Amplifier. It can manage up to 1A output current over a voltage range of -18V to +30V over a frequency range of DC - 52 MHz. This is sufficient to directly measure many power supplies. If this is not enough, you can inject across a low value series resistor (eg 0.1 ohm). This video shows you how to connect up a CS328A-FRA and CS1070 to measure the PSRR of an LTC3589 over the frequency range 200 Hz - 10 MHz.

48V Output from 125V DC Input 500mA Load Current Power Regulator
 
00:15
The project published here is an adjustable high-voltage regulator with an output 48 V DC from input supply of 125V DC. Circuit is capable to drive load current up to 500mA. This regulator circuit designed for use in high-voltage applications where standard bipolar regulators cannot be used. Excellent performance specifications, superior to those of most bipolar regulators, are achieved through circuit design and advanced layout techniques. As a state-of-the-art regulator, the TL783 device combines standard bipolar circuitry with high-voltage double diffused MOS transistors on one chip, to yield a device capable of withstanding voltages far higher than standard bipolar integrated circuits. Because of its lack of secondary-breakdown and thermal-runaway characteristics usually associated with bipolar outputs, the TL783 maintains full overload protection while operating at up to 125 V from input to output. Other features of the device include current limiting, safe-operating-area (SOA) protection, and thermal shutdown. Even if ADJ is disconnected inadvertently, the protection circuitry remains functional. Only two external resistors are required to program the output voltage. An input bypass capacitor is necessary only when the regulator is situated far from the input filter. An output capacitor, although not required, improves transient response and protection from instantaneous output short circuits. Excellent ripple rejection can be achieved without a bypass capacitor at the adjustment terminal. Output voltage fixed 48V DC but it is adjustable by changing value of resistor value R6, refer data sheet for formula to choose appropriate value of R6. LT783 and transistors required large size heat sink. Features • Supply Input 70V to 125V DC • Output 48V DC • Output Current 500mA

NMOS Low Drop-out Voltage Regulator with -17dB Wide-band Power Supply Rejection
 
19:05
A fully on-chip Low Drop Out (LDO) regulator that uses an NMOS output transistor, designed in 22FDX technology, is presented. Proposed LDO capitalizes on technological advantages of back gate bias available in 22FDX to reduce the drop out voltage for regulator and achieve wide band power supply rejection. Charge-pump is used to apply forward back-bias on the NMOS pass device to reduce its threshold voltage down to 0V and enable low drop out regulation. The LDO generates 0.91V output from 1.35V input supply with load current capacity of 15mA. Proposed LDO provides wide band power supply rejection achieving worst case PSR of -17dB across 1Hz-10GHz frequency spectrum essential for SerDes applications. Unity gain bandwidth of above15MHz is achieved along with fast transient response of 63mV peak-to -peak for a current step of 14mA in 100ns.

Unlike the half-wave rectifier, the full wave rectifier gives output during both half cycles. Hence, the average or DC value of the output signal is more than the signal which is rectified using a half-wave rectifier. In this video, the following full wave rectifier circuits have been explained. 1) Center tapped full wave rectifier 2) Full wave bridge rectifier The output of the Full wave rectifier is pulsating DC. The ripple in the output waveform can be reduced using the filter. To remove or reduce the ripple from the output waveform, the RC time constant of the filter circuit should be much larger than the time period of the Full wave rectifier. Parameters of the Full wave rectifier: Average Value: 2Vm / π RMS Value: Vm/√2 Ripple Factor: 0.48 Efficiency: 81.2 % PIV: 2Vm (Center tapped Full-wave Rectifier) PIV: Vm (Full wave Bridge Rectifier) Output Frequency: 2f The link for the other useful videos related to diode: 1) Half-Wave Rectifier: https://youtu.be/Ll0IOk_Ltfc 2) How to solve the diode circuits: https://youtu.be/jkEVGQ2lneI 3) RMS and Average Value: https://youtu.be/qDHsokTcgck This video will be helpful to all students of science and engineering in understanding the Full Wave Rectifier Circuits. #FullWaveRectifier #FullWaveBridgeRectifier #CentertappedFullWaveRectifier Follow me on YouTube: https://www.youtube.com/allaboutelectronics Follow me on Facebook: https://www.facebook.com/ALLABOUTELECRONICS/ Follow me on Instagram: https://www.instagram.com/all_about.electronics/ Music Credit: http://www.bensound.com/

Oscilloscope Averaging
 
03:51
Get professional PCBs for low prices from www.pcbway.com --~-- About a month ago we published a video on measuring power supply ripple with an oscilloscope. Someone mentioned in the comments that we should have used the averaging function on the scope. So in this video we take a look at how to use an oscilloscope averaging function, along with a high frequency rejection to produce a cleaner waveform.

Low Noise Rail-to-Rail Negative Regulator with Programmable Current Limit
 
05:22
with Amit Patel Design Engineer, Power Products The LT®3090(http://www.linear.com/LT3090) is a low noise single resistor programmable negative regulator based upon current reference architecture. The advantage of this architecture is that output voltage is rail-to-rail programmable while always maintaining unity gain operation. Hence, the bandwidth/transient response, noise, PSRR and load regulation are all independent of output voltage. Additionally, the LT3090 features programmable current limit, positive or negative current monitoring, programmable cable drop compensation, bidirectional shutdown capability and can be easily paralleled for higher current operation or heat spreading on surface mounted board. The LT3090's low noise and rich feature set make it ideal for a variety of applications.

Super Power
 
04:05
http://www.synthrotek.com/products/modular-circuits/super-power/ Synthrotek’s Super Power gives you loads of power and is skiffable at just 46mm deep! Designed with safety in mind, Super Power has polarity protection and regulators with short circuit, overheating, and over current protection. Why make a totally new power module? First and foremost, the Deluxe Power Module was a tough build. DIY has always been at the heart of what we do, so we re-oriented the board so that it is simpler to build, and more importantly, simpler to troubleshoot. We also would occasionally have a metal switch break when shipping a Eurorack case, so we switched to a hardy plastic jack. The new circuit allows Super Power to come in three different power configurations. Super Power Red (with red LEDs) will power a single row of 84 or 104HP, Super Power Green will power two rows of 104HP, and Super Power Blue will power three to four rows of 104HP. Features: Multiple power options to fit your needs and budget: - RED: Power one row of 84 or 104HP.* Power output: +12V @ 3A, -12V @ 2.5A, +5V @ 1.5A - GREEN: Power two rows of 104HP.* Power output: +12V @ 3A, -12V @ 1.3A, +5V @ 1.5A - BLUE: Power three to four rows of 104HP.* Power output: +12V @ 3A, -12V @ 2.5A, +5V @ 1.5A - Advanced low-noise, fully-regulated voltage converters on each rail - Over-current protection: shuts off each power rail automatically if modules use too much current on that rail - Two 16-Pin Eurorack power connectors, keyed for safety - Molex quick-release connector for easy install of Synthrotek Noise Filtering Distribution Boards - USB jack for powering an iPhone, Beat Step Pro, etc. - Input Voltage Range: 16 to 19 volts DC - Requires 16-9V power brick, DC Input Jack size: 2.1mm - Module Width: 4HP - Module Depth: 46mm
