Abstract :
This paper presents a switched-capacitor multibit ADC delta-sigma modulator for baseband demodulation integrated in a single-chip Bluetooth radio-modem transceiver that achieves 77 dB of signal-to-noise-plus-distortion ratio (SINAD) and 80 dB of dynamic range over a 500-kHz bandwidth with a 32-MHz sample rate. The 1-mm2 circuit is implemented in a 0.35-μm BiCMOS SOI process and consumes 4.4 mA of current from a 2.7-V supply
