  • Abstract
    This paper presents a fully integrated GPS receiver with 2.4 dB NF, 1.2mm2 area, and 13 mA of current in 55 nm CMOS. NF degrades by only 0.1/0.5/0.1 dB in the presence of GSM, DCS, and WiFi blockers respectively. By using current mode operation, push-pull topology, current reuse techniques, and modular Gm-TIA stages, area is about half and power is about 1/3 of previously published GPS receivers while having similar or better co-existence performance.
