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

A circuit for compensating a base current for generating a PTAT voltage, the circuit comprising:

• a first current mirror configured to supply a first collector current corresponding to a collector current of a first substrate bipolar junction transistor (BJT) to an emitter of the first substrate BJT;
• a second current mirror configured to generate a first mirroring base current corresponding to a replicate current of a base current of the first substrate BJT;
• a current transmitter configured to transmit the first mirroring base current;
• a third 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 to supply the second mirroring base current to the emitter of the first substrate BJT and configured to generate a third mirroring base current having an amount which is equal to “N” (wherein, “N” denotes a natural number which is greater than one) times an amount of the first mirroring base current to supply the third mirroring base current to an emitter of a second substrate BJT;
• and
• a second collector current transmitter configured to supply a second collector current to the emitter of the second substrate BJT where the second collector current amount is equal to “N” times an amount of the first collector current.
