Abstract :
A new automatic gain control (AGC) is described in this paper. It has a low power consumption, since it is designed in CMOS technology, and an easy external setup using reference voltage inputs. The circuit is built around an operational amplifier using MOS resistive circuits (MRC). This AGC has shown a good linearity and a very weak total harmonic distortion. Some results are included in this paper
