A 35-mW -3.6mm2 fully integrated 0.18 µm CMOS GPS radio

A 35mW- 3.6mm²GPS radio has been integrated in a 0.18µm CMOS process. Housed in a standard VFQFPN52 package, the GPS radio needs just a few external passive components for the input matching network and one external reference for the Synthesizer. The GPS receiver chain down-converts a Coarse/Acquisitions L1 signal with NF-5.3dB, conversion gain 81dB, Image Reject > 32dB. The synthesizer features a phase noise of -95dBc/Hz @1MHz offset and a total integrated phase noise of <7°rms in the [500-Hz-1.5-MHz] band. The one reported here is the smallest and most integrated GPS radio ever reported so far.
