摘要: Disclosed herein are signal amplifiers that have an input impedance varies over different bias currents. The amplifier includes a gain stage with plurality of switchable amplification branches each capable being activated such one or more the provides targeted adjustment to impedance. In addition, disclosed variable-gain configured provide levels result in values presented respective by stage. can include values. inductive elements be
