A detailed study of various variable gain topologies is presented in this report. A Variable Gain Amplifier (VGA) with an exponential gain control characteristic is desired in Automatic Gain Control (AGC) application. Thus, a metal-oxidesemiconductor (MOS) variable gain amplifier with linear in dB c...
