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 ...

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 first two parts of this blog series introduced the challenge of enabling Power Distribution Networks (PDN) to maintain a well regulated supply for sensitive components in a circuit, in the face of ...

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 ...

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 ...

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 ...

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 ...

Modern PCBs are now much more than simply a way to route signals between components; just as the skin is the largest organ in our bodies, PCBs should be thought of as the largest component in a ...
