Abstract

A new, simple gain control circuit is introduced for linear applications. It utilises a differential stage for the gain control function and a predistortion circuit to maintain linearity. The circuit provides a wide dynamic range and low intermodulation levels. Suitable applications are WCDMA cellular phone circuits such as variable-gain amplifiers or driver stages with gain control for power amplifiers.
