Keywords:
CMOS, Amplifier, AGC (Automatic Gain Control), Low Power, VGA (Voltage Gain Amplifier).Abstract
A variable gain amplifier or voltage controlled amplifier is an electronic amplifier or circuit that varies its gain depending on a control voltage. A Variable Gain Amplifier (VGA) based on the gate based design methodology is proposed in this paper. The VGA is designed using the CMOS 90nm technology with 0.35V supply voltage. The gain of the VGA is control or tuned using the control voltage. The power consumption of the VGA cell is achieved 115pW. The proposed VGA cell is cascading to achieve the better response of the VGA, in the cascading four VGA cell is used and the power consumption of the proposed VGA design is 0.95mW. The gain of the VGA is also tuned or varies using the control voltage.
