Abstract
A 5 MHz-IF digital FM demodulator integrated with a 4th-order bandpass delta-sigma front-end exhibits 74.7 dB SNR, -80.7 dB THD, and 61 dB AM rejection within a 9 kHz message bandwidth. The 0.65 μm CMOS chip occupies 3.5 mm×3.5 mm of active area and consumes 180 mW with 4 V supply and 20 MHz clock
