Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

Avoiding op-amp output saturation error by keeping op-amp outputs “live” and below zero volts is a job where a few milliamps and volts (or even fractions of one ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can do that with an op amp ...
