Abstract

The invention provides a high-voltage band-gap reference voltage source which comprises a band-gap reference core module and a high-voltage output module; the band-gap reference core module comprises a zero-temperature-coefficient current generation module used for generating a current in direct proportion to the temperature and a current in inverse proportion to the temperature when the high-voltage band-gap reference voltage source works stably, and after the two currents are superposed according to a certain proportional relation, the band-gap reference core module outputs a band-gap reference current with a zero temperature coefficient; and the high-voltage output module is used for converting the band-gap reference current with the zero temperature coefficient into high-voltage band-gap reference voltage according to an output resistor R3 and outputting the high-voltage band-gap reference voltage. The invention further provides a high-voltage band-gap reference voltage source generation method, a high-voltage fixed power supply and application of the high-voltage fixed power supply.

Description

technical field [0001] The disclosure relates to the technical field of high-voltage bandgap reference voltage sources, and in particular to a high-voltage bandgap reference voltage source and a generation method thereof, a high-voltage fixed power supply and applications thereof. Background technique [0002] Compared with traditional sensors, MEMS (Micro-Electro-Mechanical System) sensors have many advantages such as low cost, small size, light weight, low power consumption, etc., and have been used in consumer electronics, medical health, automotive electronics, industrial control, etc. The field realizes more and more applications.
