Abstract :
A dual-mode DeltaSigma ADC for a GSM/WCDMA direct-conversion receiver is implemented in a standard 65nm digital CMOS process and has a core area of 0.1mm2. With sampling frequencies of 48MHz and 96MHz, the ADC achieves peak SNDRs of 84dB and 49dB over the 100kHz GSM band and 1.92MHz WCDMA band, respectively. It draws 2.75mA in GSM mode and 3mA in WCDMA mode from a 1.2V supply
