Effective Inner Loop AGC Circuit
Pages: 41-43,46
Year: Issue:  18
Journal: Video Engineering

Abstract: 设计了一款应用于移动数字电视调谐器芯片中的数字式内环自动增益控制( Automatic Gain Control,AGC)电路.该控制电路采用的算法有效避免了死循环的问题,并且提高了AGC电路的响应时间.电路设计利用Verilog硬件描述语言进行描述,通过了功能仿真并在FPGA上进行了验证.最终采用TSMC 0.13 μm CMOS工艺,完成了电路版图.芯片面积在126 μm×106 μm,平均功...
