Abstract
A full-wave rectifier having a limited number of circuit elements comprises an amplifier, such as an operational amplifier, having an inverting input held at a reference potential, a non-inverting input receiving an input signal through a first resistor and an output, a transistor having its base connected to the output of the amplifier and its collector connected to the non-inverting input of the amplifier through a second resistor and optionally an output circuit for producing an output signal from the connection point between the collector of the transistor and the second resistor.
