Abstract
Disclosed is a system for checking the capacity of a storage capacitor with high resolution. The system is constructed to increase the precision of correlation between a sink current and a clock frequency necessary for health check of the storage capacitor. This construction enables completion of the health check in a shorter time, minimizing both energy consumption and loss of the storage capacitor. Therefore, the system can supply sufficient energy as emergency power to a main system in an emergency power situation in which power supply is cut off.
