Abstract :
A low-power GFSK demodulator employing a self-calibrated delay line and DSP circuits achieves an SNR of 14.9dB. Without any accurate analog circuits and oversampling clocks, the demodulator performs detection for frequency offsets up to plusmn350kHz. Fabricated in a 0.18mum CMOS process, it occupies 0.26mm2 and consumes 2mA from a 1.8V supply.
