摘要
介绍了数字可变增益放大器(DVGA)AD8369的电路结构及其关键技术指标,并用该芯片为数字中频接收机设计了全数字自动增益控制(DAGC)系统,给出了其控制回路及其实现算法。该DAGC系统具有收敛速度快、工作稳定性好和抗饱和能力强等特点。
This paper introduces the key specifications and its architecture of AD8369, and designs a full digital automatic gain control(DAGC) system for digital intermediate frequency receiver, and provides its control circuit and algorithm.The DAGC system has several merits, such as fast convergent rate, good operation stability and anti-saturation,etc.
