摘要

这里报告的电路构成了民用L1波段的完整GPS接收器。三转换架构最大限度地减少了在最高频率下工作的组件数量，从而减少了功耗，而第二个中频滤波器的集成将接收器的复杂性降低到与单个超级滤波器相当的水平。这种集成接收机的直接应用是为小型便携式(可穿戴)消费产品提供GPS时间参考。低功耗是主要要求。电源为2.4 V ~ 3.5 V，由锂电池供电。

A 12 mA triple-conversion receiver for GPS

The circuits reported here form a complete GPS receiver for the civilian L1 band. Triple-conversion architecture minimizes the number of components working at the highest frequency and thus power consumption, while the integration of the 2nd IF filter reduces the complexity of the receiver to a level comparable to that of a single superhet. The immediate application of such an integrated receiver is to provide GPS time reference for small, portable (wearable) consumer products. Low power consumption is a primary requirement. The power supply is 2.4 V to 3.5 V from a lithium battery.
