Second-stage output filters are often used to attenuate the output voltage ripple of a switching power supply. They can also isolate one load circuit from another. In this power tip, I will describe ...

A dc-to-dc converter regulates a varying input voltage to a (usually) fixed output voltage via a feedback control system. The feedback control system should be as stable as possible to avoid ...

For the PDF version of this article, click here. Switching power supplies rely on feedback control loops to ensure the supply maintains the required voltage and current with varying load conditions.

Nyquist-sampling theory lies at the heart of today's digital-communications systems. It requires that data-conversion systems include antialiasing input filters. Designers need to understand the ...

One of the most challenging tasks in analog circuit design is to adapt a functional block to ever new CMOS process technology. For digital circuits the number of gates per square mm approx. doubles ...
