基于VerilogHDL的DAGC电路设计

Design of DAGC based on VerilogHDL

介绍了一种无线局域网(WLAN)以及通信系统接收机中数字AGC(自动增益控制)电路的设计技术;文中包括了数字AGC电路基本原理、实现方法和仿真结果,AGC电路通常用来把一个任意的输入信号调节到任意规定的功率水平,所设计的电路性能达到了60 dB的动态范围,输出信号变化小于或等于2 dB。

This paper introduces the automatic gain control（AGC） circuit design techniques applicable to the receiver of WLAN and others. The digital AGC circuit principle, method of implementation, and simulation results are described. The AGC is usually used for regulating an arbitrary input-signal to some specified power level. Finally, the result of AGC shows that the circuit designed matches up with the 60 dB AGC dynamic range and the change of the output-signal is equal to or smaller than 2 dB steps.
