Abstract

Injection locking based QPSK demodulation have been reported in several publication, however the data rate is less than Gbps. In this paper, the theory of an oscillator injection locks to a wideband modulated signal is studied. Based on the principle study, a proof of concept QPSK coherent baseband receiver is designed and verified. The receiver is able to demodulator QPSK signal with data rate up to at least 12 Gbps, which is limited by the mixer bandwidth. The receiver has a power consumption of 210 mW. It consists of a novel injection-locked VCO (ILVCO) based carrier recovery block, which can be used for even higher data rates if the theoretical condition proposed in this paper is met.
