Abstract
Within current scaling circuitry having bipolar transistors of the same conductivity type disposed in principal master and slave paths, the negative feedback current gain around the principal master path transistor is regulated in direct proportion with the level of a current source that is independent from both of the principal master and slave paths, to substantially achieve tracking between the level of the current source and the levels of current flow through the principal master and slave paths.
