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.

Control circuits of collector current of substrate bipolar junction transistors and circuits of compensating for base current for generating a proportional to absolute temperature (PTAT) voltage using the control circuits
