摘要

为新一代定位服务设计了一个高度集成，低功耗的GALILEO/GPS前端，使用0.35 μ g SiGe工艺。该系统采用6 MHz带宽低中频架构，中频约为4 MHz。前端电压增益为103 dB, SSB噪声系数为3.7 dB，适用于高灵敏度应用。在3V电压供电的情况下，实现的功耗仅为62兆瓦，不影响性能，并且使用了最少的外部组件

A low power low noise figure GPS/GALILEO front-end for handheld applications in a 0.35 /spl mu/m SiGe process

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
