Abstract

A highly integrated, low power GALILEO/GPS front-end for the new generation of positioning services has been designed using a 0.35 mum SiGe process. It has been implemented using a 6 MHz bandwidth low IF architecture whose IF frequency is 4 MHz approximately. The front-end exhibits a voltage gain of 103 dB and present a SSB noise figure of 3.7 dB which makes it suitable for high sensitivity applications. The achieved power consumption is only 62 mW from a 3V voltage supply with no compromise with performance and with a minimal amount of external components
