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

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 2.2dB and a gain of 16dB for each band. The PLL exhibits phase noise of −90dBc/Hz at 100kHz offset frequency. The receiver consumes 26mW for a supply voltage of 1.2V while occupying a 3×3.8mm
