  • Abstract
    In this paper, a differential CMOS automatic gain control amplifier is presented. The proposed architecture uses a differential variable gain amplifier, implemented with a Gilbert cell and provides an automatic gain control amplifier for both alternations of the input signal. It yields almost 20 dB dynamic range of input 100 MHz sinusoidal signal and provides a constant differential output of 200 mVpp with AGC loop bandwidth of 1 MHz. The power consumption is 50 mW from a single 3.3 V voltage supply.
