Abstract
A super-regenerative receiver (SRR) circuit includes an amplifier configured to amplify an input injection signal and output the amplified injection signal to an oscillator; and a feed-forwarding unit configured to feed-forward, to the oscillator, a filtered signal obtained by filtering the injection signal after converting a frequency of the injection signal to another frequency; wherein the oscillator is configured to receive an input of a signal in which the filtered signal is applied to the injection signal.
