A 26mW dual-mode RF receiver for GPS/Galileo with L1/L1F and L5/E5a bands

Abstract

A CMOS RF receiver for L1/L1F and L5/E5a dual-band GPS/Galileo system is designed in a 0.13 m standard CMOS process. It can be fully integrated in System-on-Chip (SoC) solution for GPS and Galileo. The receiver includes a low-noise amplifier (LNA), down-conversion mixers, channel selection filters (CSF), 2-bit analog-to-digital converters (ADC) and the full phase-locked-loop (PLL) synthesizers as well as on-chip voltage-controlled-oscillator (VCO). The dual-band LNA achieves a noise figure (NF) of 2.2 dB and a gain of 16 dB for each band. The PLL exhibits phase noise of -90 dBc/Hz at 100 kHz offset frequency. The receiver consumes 26 mW for a supply voltage of 1.2 V while occupying a 3times3.8 mm2 die area including ESD I/Q pads.
