ABSTRACT:
An input tracking threshold detector includes a first circuit receiving input signal, a feedback signal, and a predetermined gating signal. The first circuit outputs a binary signal which during gating signal enablement intervals is indicative of the relative amplitudes of the input and feedback signals. The feedback signal is developed from the first circuit output by a second circuit whose output signal amplitude is indicative of the duty cycle of its input.
