Voltage system and operating method thereof
A voltage system and a method of operating a voltage system are provided. The voltage system includes an oscillator and a pump device. The oscillator is configured to provide an oscillation signal exhibiting a first frequency when a voltage level of a supply voltage is greater than a reference voltage level, and to provide the oscillation signal exhibiting a second frequency greater than the first frequency when the voltage level of the supply voltage is less than the reference voltage level. The pump device is configured to provide the supply voltage, based on a frequency of the oscillation signal provided by the oscillator, by performing a charging operation.
