Abstract
In this project, an automatic gain control(AGC) amplifier is analyzed and designed. It was fabricated with TSMC 0.35um 1P4M CMOS technology and the size of the chip is 0.928um×0.67895um. We use a V-V Converter to decrease the power consumption and increase dynamic range. We simulate all circuits by Hspice. The supply voltage is 3V. The dynamic range is 57dB and the noise figure is 11.2338dB. The total power consumption is 6.2664mW and the gain range of VGA is 84dB.
