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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

The rule of thumb to use a 0.1-µF capacitor on the power pin of a semiconductor device is rapidly fading away. Semiconductor products of today have multiple power pins and voltages. But, it is more ...
