A Low Power, Highly Integrated Monolithic Downconverter Circuit for GPS Applications

Carl Denig, Charles Dozier, Darren Weninger

Abstract:	As Global Positioning System receivers continue to gain market acceptance and widespread usage, the need for lower cost, higher performance receivers becomes more important. Today’s system designers are tasked with integrating the receivers into a wide variety of applications and as a result, are requiring the receiver designers to reduce part count, power consumption and overall receiver cost to ease the integration. GPS receivers have evolved into two chip architectures and it is the continued goal of the receiver designers to make the GPS receiver as inexpensive and easy to integrate as possible. This paper describes a dual conversion downconverter integrated circuit that has been developed for low cost, highly integrated GPS applications. The IC was developed with the goal of reducing the power consumption and increasing the level of integration in order to reduce the number of external components required, thus reducing the overall system complexity. The IC architecture, design implementation and measured results will be discussed in the paper.
