ABSTRACT:
In a full-wave rectifier circuit, a sinusoidal signal is applied to a differential amplifier, first and second current mirror circuits obtain outputs from the differential amplifier which are opposite in phase to each other. Outputs of the first and second current mirror circuits are applied respectively to the input and output sides of a third mirror circuit and other outputs of the first and second current mirror circuits are applied respectively to the input and output sides of a fourth mirror circuit. The connecting point of the first and fourth current mirror circuits is connected to the base of a first emitter-follower-connected transistor, while the connecting point of the second and third current mirror circuits is connected to the base of a second emitter-follower-connected transistor. The connecting points are connected to a current source circuit. The first and second emitter-follower-connected transistors have their emitters connected together, to provide a full-wave-rectified output.
