DIGITAL SUPER-REGENERATIVE DETECTOR RF RECEIVER

摘要

A digital super-regenerative receiver is provided having an analog (RF) detector (500) and a regenerative oscillator (514). The output of the RF detector (500) is used to generate a digital signal (701) 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.
