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 ...

In “Know the sometimes-surprising interactions in modelling a capacitor-bypass network” (abbreviated to “Know the…” when referred to here), Tamara Schmitz of Intersil and I provided some simulation ...

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 ...

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 ...

Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass capacitor (CBYP) is especially important. It has to support the switched ...

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 ...
