英文摘要	A CMOS wideband receiver for BD-II B2&B3 mode is presented. The chip demonstrates a noise figure of 4.0dB and a 2dB CNR desensitization point of 4dBm at 800MHz GSM blocker. Due to the optimized design of an ESD-protected LNA and a 1/f-noise-reduced high-LO-RF-isolation Mixer, the spurious level is suppressed below - 113dBm referred to the RF input. The fractional-N ???? synthesizer obtains LO phase noise of -92dBc/Hz@1KHz and -117dBc/Hz@1MHz, with the reference spurs are below -60dBc. The integrated 4th-order LPF has tunable 7.5MHz/10MHz/15MHz corner frequency. The mixed-signal AGC loop, including 4-bit ADCs, variable gain amplifier and programmable amplifier, achieves 55dB gain dynamic range. The receiver consumes 31mA from a 1.8-V supply voltage while occupying a 5.5-mm2 die area including ESD pads. ?2010 IEEE.; EI; 0
