Abstract :
A quad-band GSM/GPRS/EDGE receiver front-end including I and Q ADCs designed in 90nm digital CMOS technology is presented. The low band receiver designed for GSM850/GSM900 achieves 33dB gain, 1.9dB noise figure, 7.5dB of noise figure under blocking condition and -20dBm of in-band IIP3 with a power of 68mW, while the high band DCS/PCS receiver achieves 32dB gain, 2.2dB noise figure, 9.3dB of noise figure under blocking condition and -20dBm of in-band IIP3 with a power of 72mW. Total active area occupies 3mm2
