Abstract :
A low-complexity binary phase shift keying (BPSK) demodulator realizes ultra-low power operation without external components. Second harmonic injection-locking followed by analog multiplication is employed to recover data from a 19 GHz BPSK-modulated carrier. Measured bit error rate (BER) at 10 Mbps for the 0.35 mm2 testchip in 90 nm CMOS is comparable to classical DBPSK detection. The prototype demodulator consumes just 2.5 mW at 0.8 V, or 250 pJ/bit.
