Abstract :
A low-IF quadrature GPS receiver consisting of a VCO, mixer and variable gain LNA is implemented in 130 nm CMOS. Consuming 352 μW from a 250 mV supply, it has the lowest supply voltage for an integrated receiver reported to date. The measured noise figure is 7.2 dB with a gain of 42 dB at a 10 MHz IF frequency. At a 1 MHz offset, the VCO phase noise is -112.4 dBc/Hz, resulting in an FoM of 187.4 dBc/Hz.
