Abstract :
A complete analog front-end, with the exclusion of the frequency synthesizer, for FM broadcasting occupies 2.8 mm2 active area in a standard 0.35 mum CMOS technology. The use of current driven passive mixer and switch capacitor polyphase filter gives +100 dBmuV IIP3, 52 dB adjacent channel selectivity and +39 dB image rejection without trimming or tuning. The output noise is 390 nVparradic(Hz), with a conversion gain of about 39 dB. This front-end consumes only 5 mA from a 2.4 V supply
