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 ...

This application note covers a wide range of applications, such as half-wave rectifiers, full-wave rectifiers, peak detectors and clamps. Many of the circuits are simple in terms of component count.

A full-wave rectifier that exploits the fact that the output voltage of certain single- supply op amps is effectively “clamped” to ground is described. It’s important that the op amp you select be ...
