A 0.5-V 400-MHz Transceiver Using Injection-Locked Techniques in 180-nm CMOS

A 0.5-V 10-Mbps differential BPSK (D-BPSK) transceiver is presented in this paper. The receiver (RX) adopts a dynamic phase-to-amplitude conversion with the injection-locking technique to demodulate the received signal. The transmitter (TX) multiplexes the appropriate phases to generate the phase-modulation signal using subharmonic injection technique. This work is fabricated in TSMC 180-nm CMOS process. At 10-Mbps data rate, the RX and TX consume 0.29 mW and 1 mW, respectively. The energy efficiency of RX and TX achieves 100 pJ/bit and 29 pJ/bit, respectively. RX sensitivity is -60 dBm.
