ABSTRACT:
The present invention is directed to a full wave rectifying circuit where a single input a.c. signal is used to perform full wave rectification with enhanced accuracy. An a.c. signal is transmitted from an a.c. signal source (1) via a coupling capacitor (3) to bases of transistors (Q1, Q4) of first and second differential gain stages (S1, S2). Outputs from the first and second differential gain stages (S1, S2) are received on input terminals of first and second current mirror circuits (K1, K2). Output currents (I.sub.011, I.sub.012) from the first and second current mirror circuits (K1, K2) are converted by load resistances working as current-voltage converting means, and then, output voltage V.sub.OUT1 rectified on the full wave basis is output from an output terminal (12). Portions of the a.c. signal out of phase from each other are rectified on the half wave basis by the first and second differential gain stages (S1, S2) and then they are added, so that a single input a.c. signal can be rectified on the full wave basis, and linearity of an amplitude of an output signal related to an amplitude of an input signal can be improved.
