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.

Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems ...

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 ...

The inability to supply adequate power in time can result in intermittent board failure and hours troubleshooting in the lab. Even an IC with ample current supply can experience “power shortage” if ...

Choosing decoupling-capacitor values can seem to be a “no-brainer.” Unfortunately, even though the consequences of selecting the wrong values are often serious, the most commonly used methods usually ...

The first thing you may want to do is check if the default control loop (i.e. the PID settings that the product is delivered with) is good enough in terms of stability and load transient performance.

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 ...

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 ...

The four basic capacitor types. The key parameters involved in selecting the right capacitor for automotive designs. Advantages and limitations of electrolytic and electrostatic capacitors. Choosing a ...
