Most ICs need to be decoupled from their power supply, usually with a 0.1uF capacitor between each power pin and ground. Decoupling is usually used to remove noise and to smooth power fluctuations.

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...

Decoupling capacitors have long been an important aspect of maintaining a clean power source for integrated circuits, but with noise caused by rising clock frequencies, multiple power domains, and ...

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...

The circuit shows a DC motor controller using L6202/L6203 DMOS full bridge driver. What is the purpose of capacitor C5? A. A bypass capacitor that suppresses AC noise present on a DC signal B. A ...

CMOS technology has evolved as the top choice for chip manufacturers. There are multiple reasons for its emergence to its current status, continuous reduction in feature size being one of them. SoC ...

Mobile SoCs are progressing to finer process nodes to pack more computing power in a smaller space while slashing power consumption. These high-performance chips operate with lower supply voltages ...

We know that *CAPACITOR* is a type of passive component and is generally used to store the charge. There are different types of capacitors available in the market and each as its own importance, ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

When a crew employed by a local electric utility set out to conduct a DC hi-pot test on a new circuit breaker, the task seemed like nothing more than a routine call. Unfortunately, the events that ...
