ABSTRACT:
A digital super-regenerative receiver is provided having an analog RF detector and a regenerative oscillator. The output of the RF detector is used to generate a digital signal from which the oscillator bias is adjusted, in order to maintain the oscillator start-up time at a fixed level. The circuit senses if the start-up time is earlier or later than the predetermined start-up time and produces an output when the majority of the start times are ahead of the expected start time.
