Abstract

A CMOS variable gain amplifier (VGA) with a wide gain control range is presented. The amplifier consists of a source-coupled pair with diode connected loads and a pseudo-exponential gain control circuit. The gain is obtained by a novel wide-range pseudo-exponential circuit topology. The proposed VGA was implemented in 0.1 Sum CMOS process which exhibits a 90-dB gain control range. The VGA draws 1.87 mW power from a 1.8-V supply per stage. Its wide bandwidth reveals that this design is well suited for wideband applications as 802.15.3a.
