Abstract :
This paper presents a new superregenerative receiver architecture. This receiver uses an oscillator based on a transmission line. By periodically changing the oscillator pole locations, the receiver is able to translate the carrier phase information into a low-pass signal. This circuit may also be used as a band-pass sampler for low-level RF signals.
