LOW NOISE REFERENCE VOLTAGE SOURCE Russian patent published in 2024 - IPC H01L27/00 G05F3/02 

FIELD: electronics.

SUBSTANCE: invention can be used as part of microcircuits of analogue-to-digital and digital-to-analogue converters, radio communication and radar equipment, high-precision measuring equipment operating in a wide temperature range, requiring precision reference voltage sources with a low level of low-frequency flicker noise. Essence: the circuit design is based on bipolar transistors. The circuit implements calibration algorithms that can significantly reduce the nonlinearity of the temperature coefficient over a wide temperature range.

EFFECT: providing significant compensation for the nonlinearity of the temperature coefficient in an extended temperature range, expanding the range of supply voltages, ensuring stability of the circuit start-up, achieving a low level of low-frequency flicker noise.
