A fully integrated single input, dual-channel, single-band reconfigurable GNSS radio frequency receiver supporting GPS, BD2 and Galileo systems is designed and implemented in a 0.18 ​μm CMOS process for portable Internet of Things applications. The receiver incorporates a single RF front-end, low-power fractional-N synthesizer, and reconfigurable complex band-pass filter, which can be flexibly configured to receive GPS L1/BD2 B1 or GPS L1/Galileo E1, and any of these signals separately, and can also effectively simplify the design complexity of the receiver and reduce power consumption. Moreover, a flexible frequency plan is employed to meet the different frequency requirements of the receiver. While drawing 16 ​mA current from a 1.8 ​V supply, this RF receiver achieves a total noise figure of 1.79 ​dB, a maximum voltage gain of 108 ​dB, a gain dynamic range of 56 ​dB and the input third-order intercept point of $-18.09$ dBm and $-23.66$ dBm at 1575 ​MHz and 1561 ​MHz, respectively, with an active die area of 1.86 ​mm².
