A 5.4mW GPS CMOS Quadrature Front-End Based on a Single-Stage LNA-Mixer-VCO

A GPS RF front-end combines the LNA, mixer, and VCO in a single stage and can operate from a 1.2V supply. The chip is implemented in a 0.13mum CMOS process and occupies 1.5mm2 active area. It consumes 5.4mW with a 4.8dB NF, 36dB gain, and a P1dBof -31dBm
