SOURCE OF REFERENCE VOLTAGE Russian patent published in 2014 - IPC G05F1/56 

FIELD: electricity.

SUBSTANCE: device contains five transistors, two resistors and current source coupled between the power supply bus and output terminal, bases of the first and second transistors are connected to collectors of the first and fifth transistors, the first resistor is coupled between the common bus and emitter of the second transistor, the second transistor is coupled between the output terminal and connected emitters of the fourth and fifth transistors, emitters of the first and third transistors are coupled to the common bus, bases of the third, fourth and fifth transistors are joined with collectors of the first and fourth transistors, a collector of the third transistor is connected to the output terminal.

EFFECT: obtainment of thermally stable output voltage at values closed to double energy gap width.
