Abstract

A dual-channel fully integrated RF receiver is designed and implemented for next generation Global Navigation Satellite Systems (GNSS) in a 0.18μm CMOS process. Its two independent channels are capable of receiving 2MHz, 4MHz or 20MHz bandwidth signals around 1.2GHz and 1.57GHz, for GPS, Galileo, and Compass systems. Gain controls along with an all-digital automatic gain control (AGC) loop are implemented in each channel to improve the noise and anti-interference performance of the receiver. While drawing 25mA current per channel from a 1.8V supply, this receiver achieves a total noise figure of 2.5dB/2.7dB and a maximum voltage gain of 115dB/112dB at 1.2GHz/1.57GHz, respectively, with a die area of 2.4×3mm² including ESD and I/O pads.
