Half-wave rectifier circuit
Description
February 9, 2020
The precision half-wave rectifier inverts & transfers the negative-half input of a time varying input signal to its output. By aptly selecting the feedback resistor values, different gains can be achieved. Precision half-wave rectifiers are often used with op amp circuits such as a peak-detector or bandwidth limited non-inverting amplifier to produce a DC output voltage. This configuration has been designed to work for sinusoidal input signals between 0.2mVpp-4Vpp at frequencies up to 50kHz.
