Previous articles in Planet Analog make mention of the “aliasing effect.” Most EEs agree in the importance of the aliasing effect as a noise source and take for granted that anti-aliasing filters are ...

Zero-drift operational amplifiers have proven to be valuable problem solvers due to their low input offset voltage and minimal input offset voltage drift. Rail-to-rail input versions of these ...

Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...
