Chop the noise gain to measure an op amp’s real-time offset voltage introduces a new type of chopping. “Chopping the noise gain” is a simple way to measure the offset voltage in real time, so that you ...

Op amps excel at providing many useful and clever solutions to routine or complicated circuit functions. A summing circuit is a perfect example. A summing circuit is typically used in applications ...

One of the most popular sections of Electronic Design in both print and on the Web over the years has been Ideas for Design (IFDs). We’d like to celebrate this department by dedicating this entire ...

This article discusses the low current input circuit ideas using the 6N139 series optocouplers. A few of the circuit designs are signal detection, transient detection, matrices and non-loading line ...
