    Abstract: A super-regenerative receiver uses controlled Q-quenching and may limit the resonant tank circuit amplitude by loading the tank circuit as soon as regenerative oscillation is detected. An amplitude detector is coupled to the regenerative amplifier and controls a Q loading circuit coupled to the tank circuit of the regenerative amplifier. The amplitude detector turns on the Q loading circuit which then stops the regenerative amplifier from oscillating, and the Q-loading remains on for a brief time to insure that the regenerative amplifier has stopped oscillating. After the brief time, the Q loading circuit is turned off and the regenerative amplifier goes into oscillation again. This cycle repeats controllably over and over, resulting in a lower self-induced noise floor and improved received signal sensitivity. The super-regenerative receiver may be used in the very low frequency (VLF), low frequency (LF), medium frequency (MF), high frequency (HF), very high frequency (VHF) and super high frequency (SHF) ranges to receive continuous wave (CW), amplitude modulated (AM) and frequency modulated (FM) radio signals.

    Abstract: A super-regenerative receiver is provided with a regenerative oscillator controlled by a frequency sweep circuit to control the bandwidth at which the receiver can receive a signal. A quench control circuit controls both the regenerative oscillator and the frequency sweeping circuit to “turn on” at the same time. The frequency sweep circuit forces the regenerative oscillator to function as a center frequency movable bandpass filter allowing the receiver to automatically tune to the actual transmitter frequency ftx to provide the best reception. This allows the receiver/filter bandwidth to be very narrow. The receiver operates as an amplitude detector, as well as a frequency or phase detector, thereby allowing the same receiver to detect AM (ASK) signals and FM or FSK signals without adding a frequency discriminator.
