FIELD: electricity.
SUBSTANCE: invention can be used as reference voltage source in generating analogous integrated circuits (IC), for example, operating amplifiers, power amplifiers, IC motor drivers, analog-to-digital converters (ADC), digital-to-analog converters (DAC) etc. Device comprises operating amplifiers (1, 4, 10, 12, 15), resistors (2, 3, 5, 6, 8, 11, 13, 14, 16-21) and diodes (7, 9). Value of the reference voltage depends on the correlation of the resistors resistance ratings and the ratio of the squares of the diodes p-n junctions.
EFFECT: decreasing influence of mechanical tolerance of elements on output voltage value and improving thermal stability in operating temperatures range.
