A dual-channel GNSS receiver for GPS and Beidou applications
This paper presents a dual-channel GNSS receiver covering GPS and Beidou on a single chip in 0.13μm CMOS process. The receiver incorporates one reconfigurable RF front-end and two separate IF signal channels with one single fractional-N frequency synthesizer by using a ring voltage-controlled oscillator. This architecture supports an external active or passive antenna and provides the benefits of low cost and power consumption. An optional SAW filter can be inserted between the low-noise amplifier and mixer, providing out-of-band interference rejection in high performance applications. The receiver exhibits maximum gain of 95 dB and noise figures of 3.5 and 3.7 dB for L1 and B1 bands, respectively. The total power consumption of the receiver is 30 mW with a 1.2-V supply while occupying a 1.7mm2 die area including the ESD I/O pads. The one presented here is the smallest dual-channel GNSS receiver reported so far.
