Abstract
A circuit and method for producing a signal that is nearly a perfect full wave rectified version of an applied alternating signal. The circuit comprises first and second identical non-linear symmetrical rectifiers each having a respective output coupled to a current mirror circuit. In response to the alternating signal being applied to the input of the first rectifier a full wave rectified signal is produced at the output thereof to drive the current mirror such that at the output thereof, which is coupled to the output of the second rectifier, there appears a signal identical to the output from the first rectifier. This signal is utilized to produce an input signal to the second rectifier to constrain the output signal therefrom to be identical to the output signal from the current mirror circuit. The input signal to the second rectifier is thus a perfect full wave rectified version of the input signal applied to the first rectifier.
