Abstract
A full wave rectifier comprises positive and negative supply lines, and a differential input amplifier which is powered by the positive and negative supply lines and which has its inverting input terminal connected through an impedance to an input terminal to which the a.c. signal to be rectified is fed. The non-inverting input terminal of the differential input amplifier is connected to a terminal at a potential intermediate the positive and negative supply lines, and a transistor has its base connected to the output terminal of the differential input amplifier. The emitter and collector of the transistor are connected through resistors to the supply lines, while the emitter of the transistor is also connected through an impedance to the inverting input terminal of the differential input amplifier, the output of the full wave rectifier being taken from the collector of the transistor.
