Booster including charge pumping circuit with its electric power consumption reduced and method of operating the same |
摘要 |
A booster is composed of a switching circuit outputting a clock signal and a charge pumping circuit boosting an input voltage to generate an output voltage in response to the clock signal. The switching circuit selects one from among frequencies as a frequency of the clock signal in response to the output voltage.
