Abstract
A conventional regenerative comparator is modified by including a transistor switch in the feedback network to open circuit the feedback path according to the output state of the comparator, and by biasing the noninverting input of the comparator with a voltage directly proportional to the amplitude of the input signal, thereby providing variable threshold comparator with a hysteresis transfer characteristic with two distinct state change threshold levels that are a fixed ratio of the amplitude of the input signal.
