SOURCE OF REFERENCE VOLTAGE DETERMINED THROUGH ENERGY GAP DOUBLED WIDTH Russian patent published in 2013 - IPC G05F1/56 H03F1/30 

FIELD: electrical engineering.

SUBSTANCE: device contains five transistors, three resistors and a current source which is placed between the power supply bus and the output terminal; the first and the second resistors, via their first outputs, are connected to the output terminal; the bases of the first and the second transistors are connected to the collectors of the first and the fifth transistors; the third resistor is placed between the common bus and the second transistor emitter; the emitters of the first and the third transistors are connected to the common bus; the collector of the third transistor is connected to the output terminal; the bases of the third, the fourth and the fifth transistors are connected to the collectors of the second and the fourth transistors; the emitter of the fourth transistor is connected second output of the second resistor; the emitter of the fifth transistor is connected to the second output of the first resistor.

EFFECT: obtainment of thermally stable output voltage at values closed to doubled energy gad width.
