Abstract:
A super-regenerative digital radio frequency receiver for receiving a radio frequency signal comprising:a regenerative radio frequency oscillator for receiving radio frequency signals and for oscillating in response thereto and producing an oscillator signal;an enable circuit coupled to said radio frequency oscillator for enabling oscillations of the radio frequency oscillator from time to time;a multi-level threshold detecting circuit coupled to receive an output of the radio frequency oscillator, the threshold detecting circuit receiving the radio frequency signal and determining when the radio frequency signal from the radio frequency oscillator due to increasing oscillation therein exceeds a threshold, the threshold detecting circuit providing a threshold output signal as a result thereof, the multi-level threshold detector circuit being coupled to the enable circuit to disable the radio frequency oscillator; anda digital detector connected to the output of the threshold detector for providing a bit signal therefrom in response to the digital detector receiving at least n of m recent threshold output signals.
