Abstract
The present disclosure provides a negative voltage generating circuit having an automatic voltage adjustment function, including a negative voltage generating circuit and a feedback control module. The negative voltage generated by the negative voltage generating circuit is adjusted by the feedback control module. The negative voltage generating circuit having the automatic voltage adjustment function of the present disclosure can automatically adjust the charge current of the charge pump according to the load current, thereby realizing the stability of the output voltage, such that the traditional analog circuit structure can work normally under the extremely low power supply voltage, and is particularly suitable for the deep submicron process. The present disclosure also realizes the digital adjustment of the output voltage, the negative voltage output is no longer single, and can be adjusted according to actual needs.
