Abstract

A novel technique for the implementation of a single chip navigation/location receiver is disclosed. For example, the receiver derives GPS and GLONAS signals without requiring any external RF image rejection filtering or IF channel select filtering and hence is a fully integrated, single chip device that lends itself to CMOS implementation. The combination of low parts count and CMOS implementation leads to a low cost navigation/location receiver. The receiver is applicable to the growing consumer location market place and operates in urban environments often with limited view of the sky. As disclosed, the multiple band receiver has two chips, RF and Digital Signal Processor (DSP). The use of full RF integration on CMOS however is an excellent starting point for an ultimate RF plus DSP receiver on a single chip.
