Abstract

A dual-mode RF receiver with low-IF architecture has been developed for L1-band GPS and Galileo in a 0.18 mum CMOS process. The channel selecting bandpass filter centered at 4.092 MHz has programmable bandwidth (2MHz, 4 MHZ, and 6 MHz), which allows the reception of GPS and Galileo signals. A fractional-N phase locked loop generates local oscillator, allowing multiple reference clock frequencies. The noise figure of the receiver is 4.5 dB while consuming 41.4 mW from a 1.8 V supply. The image signal is rejected by more than 34 dB.
