Abstract
A squaring amplifier circuit (300) generates a substantially rectangular output signal from an a.c. input signal. An amplifier stage (303) is biased at a low quiescent current by a current source network (305) and a coupling network (306). Since the amplifier stage (303) current is a non-linear function of its input voltage, application of a low-level a.c. input signal (313), through an input signal coupling network (302), results in a substantially rectangular output signal having frequency and duty cycle that are substantially identical to the frequency and duty cycle of the input signal.
