A compact low-power low-voltage CMOS variable gain amplifier (VGA) is proposed. The proposed circuit merges a source-degenerated transconductance amplifier with a current-mode transimpedance amplifier, which renders voltage gain control with constant bandwidth. Coarse gain tuning is achieved by using a...
