This paper reports a wideband inductorless automatic gain control (AGC) amplifier for wireline applications. To realize a dB-linear AGC range, a pseudo-folded Gilbert cell driven by a single-branch negative exponential generator (NEG) is proposed as the core variable-gain amplifier. The NEG features...
