Abstract

A phase-shift keying (PSK) demodulator is demonstrated for the target application of low power and high data rate inductive links. The demodulator based on the single-bit sampling demodulation scheme is capable of operating in binary, quadrature, 8-, and 16-PSK mode. The prototype chip realized in 0.18-μm CMOS process can demodulate up to 1.25 MSymbol/s at 5-MHz carrier frequency. It occupies 240×310 μm2 and consumes 140 μA from 1.2 V.
