Abstract: This paper describes a CMOS dB-linear variable gain amplifier (VGA) that can provide a variable gain of 60dB while maintaining its 3 dB bandwidth greater than 10MHz. A novel exponential circuit is proposed to obtain the dB-linear control characteristics. The non-ideal effects on dB linearity are analyzed and the corresponding compensation methods are suggested. Simulation results based on 0.35-μm CMOS technology are presented to demonstrate the performance of the proposed dB-linear VGA.
