Abstract :
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.
