A 65nm CMOS quad-band SAW-less receiver for GSM/GPRS/EDGE

A quad-band 2.5G receiver integrates the front-end SAW filters, the LNA matching, as well as the RF baluns, achieving a typical sensitivity of close to −111dBm. Utilizing an arrangement of only four baseband capacitors and MOS switches driven by 4-phase 25% duty-cycle clocks, high-Q BPF's are realized to attenuate the 0dBm out-of-band blocker. The SAW-less receiver draws 55mA from the battery, and measures an out-of-band 1dB-compression of greater than +2dBm.
