Abstract
An integrated circuit includes a base current cancellation circuit and a complementary to absolute temperature (CTAT) circuit. The base current cancellation circuit includes a first bipolar junction transistor (BJT) and a current mirror coupled to the first BJT. The current mirror is configured to provide a mirrored current to a base electrode of the first BJT. The CTAT circuit is coupled to receive a voltage signal corresponding to a reference current of the current mirror. The CTAT circuit includes a second BJT coupled to form a base current based on the voltage signal.
