Patent ID: 7263138

Claim:
A super-regenerative receiver, comprising: a quenchable oscillator, said quenchable oscillator having a tuned circuit approximately resonant at a frequency of a desired signal and a signal output; a quench circuit having a control input with first and second logic states, said quench circuit being coupled to the tuned circuit of said quenchable oscillator when the control input is in the first logic state, and said quench circuit being decoupled from the tuned circuit of said quenchable oscillator when the control input is in the second logic state; and a signal detection circuit, said signal detection circuit having an input coupled to the signal output of said quenchable oscillator and a control output coupled to the control input of said quench circuit, wherein if a signal level from the signal output is greater than a certain value then the control output of said signal detection circuit is at the first logic level and if the signal level from the signal output is equal to or less than the certain value then the control output of said signal detection circuit is at the second logic level.
