Abstract
A 40-dB dynamic-range variable-gain amplifier (VGA) designed for the code d ivision multiple access (CDMA) cellular phone has been developed, A wide-dy namic-range VGA under a low control voltage of 2.0 V, compatible with high linearity and low distortion characteristics, essential for CDMA, is realiz ed by the nem gain control technique. It greatly contributes to the high pe rformance and small size of RF circuits for CDMA cellular handsets.
