Band gap circuit

摘要

The present invention relates to a band gap circuit for providing an integral multiplication of an elementary band gap voltage. The circuit comprises a first transistor having its base connected to its collector via a resistor, a second transistor which is connected at its base to the collector of the first transistor, and a third transistor which is connected at its base to the collector of the second transistor, with the emitters of the three transistors being connected to one pole of a supply source. A fourth transistor is provided in emitter follower configuration and connected between the emitter of the fourth transistor and a connection point, is a series connection comprising at least one resistor and at least one diode.
