This paper describes a new technique for realizing CMOS digitally controlled, dB-linear variable gain amplifier (VGA) circuit. The circuit is developed taking into account system level issues for a direct conversion receiver. Beside being effective and simple to use from a system point of view, the developed VGA offers precise gain control, high linearity and low power consumption. The circuit can operate in a current domain or a voltage domain mode with single ended or fully differential signal handling capability. The proposed VGA circuit is implemented using a novel class AB operational transconductance amplifier and current division networks. Simulation results are included.

Index Terms:

Automatic gain control, Variable gain amplifier, dB-Linear.
