ABSTRACT:
A transistor built on a substrate employs two collectors, an output collector and a secondary collector. The purpose of the secondary collector is to collect minority carriers at saturation and feed these minority carriers back to the input reference of a current mirror. This saturation current causes a decrease in the current through the input reference transistor and decreases the current in the output of the current mirror responsively, driving it away from saturation.
