Abstract
A voltage scaling system can include an oscillator, a power management unit, a frequency meter, a table unit and a control unit. The oscillator is used to generate a clock signal according to a code and a power signal. The power management unit is used to generate the power signal according to a first control signal corresponding to a requested voltage. The frequency meter is used to measure a frequency of the clock signal and generate a second control signal accordingly. The table unit is used to generate a minimum code. The control unit is used to generate the code and the first control signal according to the second control signal, the minimum code and a target frequency.
