Abstract
A circuit for controlling a collector current of a substrate bipolar junction transistor (BJT) is provided. The circuit includes a first current mirror configured to generate a first mirroring base current corresponding to a replicate current of a base current of the substrate BJT, a current transmitter configured to transmit the first mirroring base current, a second current mirror configured to generate a second mirroring base current corresponding to a replicate current of the first mirroring base current received from the current transmitter and configured to supply the second mirroring base current to an emitter of the substrate BJT, and a current source configured to supply a drive current corresponding to a collector current of the substrate BJT to the emitter of the substrate BJT.
