A simple yet effective approach for variable-gain amplifier (VGA) design with accurate dB-linear characteristic is presented. In order to extend the bandwidth of the designed VGA with a minimized footprint, an inductorless-based approach is adopted. Moreover, a unique approach that exploits a self-c...
