Abstract :
A merged LNA and mixer with an on-chip VCO is fabricated in 0.35 /spl mu/m CMOS for a 2.1 GHz WCDMA receiver. The front-end consumes 8 mA from 2.7 V and gives NF of 3.2 dB, conversion gain of 24.2 dB, and input IP3 of -1.5 dBm. The VCO consumes 3 mA while achieving phase noise of -128.4 and -138.5 dBc/Hz at offsets of 5 and 15 MHz, respectively.
