Abstract :
This 0.6 /spl mu/m BiCMOS IC mixes a 10-300 MHz first IF down to a 1.5-3 MHz second IF and digitizes the result with a bandpass sigma-delta ADC. The ADC achieves 88 dB SNR in a 10 kHz bandwidth, 75 dB SNR in a 200 kHz bandwidth and >90 dB of image rejection while consuming only 8 mA from a 2.7 V supply. The complete IC, which incorporates an LNA, mixer, active anti-alias filter, VGA, ADC, decimation filter and two synthesizers, achieves a noise figure of 11 dB and an IIP3 of -1 dBm with a power consumption of 120 mW.
