ABSTRACT:
A double half-wave rectifier circuit with earth shift using an input differential amplifier and two current mirrors in cascode configuration in such a way that the input current is transferred to the output via one or the other of the current mirrors depending on whether the input signal voltage is greater than or less than an input reference voltage and therefore the current is positive or negative.
