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 ...

An electrical device that converts alternating current (AC) to direct current (DC) is the rectifier. The simple process of rectification produces a type of DC characterized by pulsating voltages and ...
