摘要：
This paper presents a low power, high sensitivity Gaussian frequency shift keying(GFSK) demodulator with a flexible frequency offset canceling method for wireless networks for industrial automation process automation(WIA-PA) transceiver fabricated in 0.18 m CMOS technology. The receiver uses a low-IF(1.5 MHz)architecture, and the transmitter uses a sigma delta PLL based modulation with Gaussian low-pass filter for low power consumption. The active area of the demodulator is 0.14 mm2. Measurement results show that the proposed demodulator operates without harmonic distortion, deals with˙180 k Hz frequency offset, needs SNR only 18.5 d B at 0.1% bit-error rate(BER), and consumes no more than 0.26 m A from a 1.8 V power supply.
