Low-temperature drift hysteresis comparator

The invention discloses a low-temperature-drift hysteresis comparator, and belongs to the field of analog circuits. The low-temperature-drift hysteresis comparator comprises a compensation current generation module and an internal hysteresis comparison module. The compensation current generation module generates compensation current influenced by the technology, the compensation current generated by the compensation current generation module is provided for the internal hysteresis comparison module, and the internal hysteresis comparison module can generate the compensation current on the basis of achieving the hysteresis transmission characteristic. The low-temperature-drift hysteresis comparator which is low in influence of process and temperature is realized through cooperation of the modules, and the accuracy of the hysteresis comparator can also be ensured for application scenes with a wide temperature range. 本发明公开一种低温漂迟滞比较器，属于模拟电路领域。所述低温漂迟滞比较器包括补偿电流产生模块和内部迟滞比较模块；所述补偿电流产生模块产生受工艺影响的补偿电流，将该模块产生的补偿电流提供给所述内部
