The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

In this paper, we propose a new methodology to enhance SoC signal integrity with respect to power/ground voltage transients, without degrading its performance. The underlying principle of the proposed ...

In some power-supply applications, the pulse-width-modulator (PWM) controller is powered up from an auxiliary winding tapped off the power stages transformer (Fig. 1).

For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies us… ...

Supply Modulator (SM): A circuit that regulates the voltage provided to a power amplifier, optimising its performance in line with the varying envelope of the transmitted signal.

This article presents a fast-transitioning power supply modulator (PSM) which is proposed to be used in envelope tracking(ET) systems for high bandwidth millimeter-wave RF power amplifiers (PA) ...

“They don’t build ’em like they used to.” There’s plenty of truth to that old saw, especially when a switch-mode power supply from the 1940s still works with its origi… ...

Capacitors C1 and C2 are power-supply bypass capacitors to help isolate the 555 timer (U1) from noise on the power line. Likewise, C3 and C4 bypass op-amp U2.

Incorporating fault injection and indication into the circuit schematic and layout can help streamline subsequent testing. I hope these examples inspire you to help make your own design verification ...

In this video, we will showcase a universal input (85V-260V AC) to 12V-3A DC Flyback power supply, delivering 36W of stable output power. The design uses an affordable PWM controller and an external ...
