FREQUENCY-MODULATED CARRIER RECEIVER USING INJECTION-LOCKED OSCILLATOR |
| 摘要 |
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. |

1. A frequency-modulated carrier receiver (100), comprising:
a signal extractor (110), configured to operably receive a frequency-modulated carrier (Fin) and generate an injection signal (Sin) based on the frequency-modulated carrier (Fin), so that the injection signal (Sin) has a relatively smaller frequency variation than the frequency-modulated carrier (Fin); and an injection-locked oscillator (120), coupled with the signal extractor (110), configured to operably conduct a band-pass filtering operation on the injection signal (Sin) to filter out noise components from the injection signal (Sin) to generate an output signal (Fout) having same frequency of a target frequency signal (Ft) in the frequency-modulated carrier (Fin). |
