A 1.571GHz LC VCO with optimized spiral inductor for GPS receiver is designed in 130nm CMOS process. The phase noise of the VCO has been reduced the use of high Q inductor and on chip filter. It has phase noise of -91dBc/Hz, -111dBc/Hz, and -131dBc/Hz at 10kHz, 100kHz, and 1MHz offset frequencies from the carrier, respectively. This VCO consumes 2mA from a 0.6V supply.
