The precise rectifier circuit with the integrating sub-circuit

Published:2011/6/19 3:36:00 Author:Seven | Keyword: precise rectifier, integrating sub-circuit

This circuit can switch the input DC signal into the DC signal. If the input signal is in a very low frequency, the input terminal capacitor C1 can be omitted. In the forward half-cycle, the output terminal of op-amp IS1 is connected by diode D1, and it is separated in the same phase by D2. The op-amp IS2 is working as the inverting voltage follower. In the backward half-cycle, IS1 is the phase inverter and it is connected with the summing point by R2. On the input terminal, R3 and R2 compose a passive feedback circuit.   (View)
