A 0.18 /spl mu/m CMOS single-chip fully integrated quad-band GSM/GPRS transceiver is presented. The low-IF receive section achieves -110dBm sensitivity at the antenna and -15dBm IIP3. The offset-frequency PLL transmitter achieves 1.2/spl deg/ rms phase noise, -65dBc modulation mask at 400kHz, and -165dBc/Hz noise at 20MHz. The chip occupies 17mm/sup 2/ and dissipates 95mA/112mA in receive/transmit...
