ABSTRACT:
A single input oscillator circuit which provides an oscillating output signal in response to the presence of an input signal is provided. A differential comparator stage having a predetermined trip point established by a reference voltage is connected between the input terminal and a set-reset latch circuit. A gain stage has an input connected to the input termial, and variable bias is derived from both the differential stage and a set-reset latch circuit for providing the output signal in response to the voltage level of the input signal. A discharge portion is connected to the input terminal to periodically couple the input terminal to a voltage potential node in response to the latch circuit.
