Redundancy backup processing method and redundancy backup control circuit of capacitor

Abstract

The invention provides a redundancy backup processing method and a redundancy backup control circuit of a capacitor. The redundancy backup processing method of a capacitor comprises the following steps of: detecting the fluctuating condition of a power supply in a circuit; and automatically adding a backup filtering capacitor in the circuit according to the fluctuating condition of the power supply. The redundancy backup control circuit of a capacitor comprises a detecting module and a redundancy backup control module, wherein the detecting module is used for detecting the fluctuating condition of the power supply in the circuit; and the redundancy backup control module is used for automatically adding the backup filtering capacitor in the circuit according to the fluctuating condition ofthe power supply. The embodiment of the invention learns the backup filtering capacitor automatically added into the circuit when the filtering capacitor is invalid by detecting the fluctuating condition of the obtained power supply, thereby greatly reducing the maintenance cost and improving the integral performance of electronic equipment.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular, to a capacitor redundancy backup processing method and a control circuit thereof. Background technique [0002] As the functions of electronic devices become more and more powerful, the degree of integration inside the chip becomes higher and higher, and the power consumption of the chip also increases accordingly. In order to reduce the power consumption of the chip and improve the working efficiency of the chip, the power supply voltage of the chip becomes lower and lower. However, under the same power consumption condition, the reduction of the power supply voltage of the chip leads to an increasing power supply current of the chip, and its ability to resist noise interference is also reduced. Therefore, the chip has higher and higher requirements on the stability of the power supply voltage. [0003] In the prior art, in order to stabilize th...
