Transceiver architecture and methods for demodulating and transmitting phase shift keying signals

摘要

A transceiver is described. The transceiver includes a first injection-locked oscillator and a second injection-locked oscillator. The transceiver also includes a first phase-locked loop coupled with the first injection-locked oscillator. The first phase-locked loop is configured to generate a first frequency reference. Further, the transceiver includes a second phase-locked loop coupled the second injection-locked oscillator. The second phase-locked loop is configured to generate a second frequency reference. The transceiver includes a mixer configured to receive the first phase-locked loop output and configured to receive said second injection-locked oscillator output. The mixer is also configured to generate a carrier frequency signal based on the first injection-locked oscillator output and the second injection-locked oscillator output. And, the transceiver includes a modulator configured to receive said carrier frequency signal.
