Abstract
A circuit for producing output pulses in response to an alternating signal supplied to the input thereof which is comprised of a pair of complementary transistors cascoded between a pair of current mirror circuits which source and sink currents to and from a common terminal respectively. The alternating input signal is applied to the interconnected emitters of the two transistors thereby rendering one more conductive while the other is rendered less conductive and vice versa. The currents which are sourced or sunk at the common terminal are proportional to the currents flowing in the two transistors and are compared to cause an output transistor to switch operating states thereby producing the output pulse.
