一种应用于导航接收机的高动态低功耗rAGC系统设计

摘要

设计一种可应用于GPS/BDS兼容导航接收机的自动增益控制系统.在SMIC 0.18μm CMOS工艺下,可编程增益放大器动态范围达到59dB,系统输出功率误差不超过3.671dBm.%This paper presents a design of an automatic gain control system which can be applied in the GPS/BDS dual system compatible receiver. The design is fabricated based on SMIC 0.18μm CMOS process. The dynamic range of programmable gain amplifier is 59dB, and the output power error of the system is less than 3.671dBm.
