Abstract In this paper, a 1.57 GHz RF receiver front-end architecture and circuits are proposed for L1 band GPS receiver applications. The presented RF receiver front-end consists of a low noise amplifier, a two-stage RF polyphase filter, and an I/Q passive down-conversion mixer, an IF transimpedance amplifier, and a two-stage IF polyphase filter. The proposed 1.57 GHz RF receiver front-end is implemented in a 130 nm CMOS process and consumes 3.4 mW at 1.2 V supply voltage. The implemented RF receiver front-end has a conversion gain of 42 dB and a DSB noise figure of 3.8 dB.
