A 115 mW CMOS GPS receiver
The Global Positioning System (GPS) provides accurate positioning and timing information that is useful in many applications. In particular, portable consumer GPS applications require cheap compact low-power receivers. This 115 mW receiver, implemented in an analog 0.5 /spl mu/m CMOS technology, comprises the entire radio-frequency (RF) and analog sections in addition to the local oscillator (LO) frequency synthesizer and a pair of oversampled A/D converters.
