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 ...

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 ...

The LICA series of low-inductance ceramic decoupling capacitor arrays fit high-reliability commercial, industrial, military, and aerospace applications and are tested to MIL-PRF-123. The series has ...

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 ...

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 ...
