Abstract

<abstract abstract-type="author" id="ab0005"> <title id="sect0005">Abstract</title> <sec> <p id="sp0050">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.</p> </sec> </abstract>
