    Abstract: A frequency-modulated carrier receiver includes a signal extractor and an injection-locked oscillator. The signal extractor is configured to operably receive a frequency-modulated carrier and generate an injection signal based on the frequency-modulated carrier, so that the injection signal has a relatively smaller frequency variation than the frequency-modulated carrier. The injection-locked oscillator is coupled with the signal extractor and configured to operably filter out noise components in the injection signal to generate an output signal.
