Abstract
A half-wave rectifier including an input port for receiving an incoming AC signal, an output port for outputting a half-wave rectified signal, an operational amplifier including inverting and non-inverting input terminals and an output terminal, the inverting input terminal connected to a ground reference and a non-inverting input terminal coupled to a negative feedback loop and a first resistor. The negative feedback loop including a second resistor coupled between a first node and a second node, the first node coupling the output terminal and the output port and the second node coupling the non-inverting input terminal and the second resistor. A capacitor is coupled to the input port and in series with the first resistor.
