摘要

采用0.18 μ m SiGe BiCMOS技术实现了与蜂窝收发器共存的GPS接收器，占用3.24 mm2。该器件集成了多相滤波器，VGA, adc，分数n合成器，LNA和混频器，最大限度地减少了脱敏和互反混频器。接收器从1.8V电源中消耗20mW，并具有1dB增益脱敏，具有-8dBm 1.9GHz阻挡器

A 20mw 3.24mm2 fully integrated gps radio for cell-phones

A GPS receiver that can coexist with cellular transceivers is implemented in a 0.18mum SiGe BiCMOS technology and occupies 3.24mm 2. The device integrates polyphase filters, VGA, ADCs, fractional-N synthesizer, LNA, and mixers, minimizing desensitization and reciprocal mixing. The receiver consumes 20mW from a 1.8V supply and has 1dB gain desensitization with a -8dBm 1.9GHz blocker
