Circuit for adjusting operating voltage of a chip |
摘要 |
The present invention provides a circuit for adjusting operating frequency of a chip, and comprises an oscillator, a controlling circuit, and a voltage adjusting circuit. The oscillator is coupled to the chip for outputting a testing clock signal according to a voltage signal. The controlling circuit is coupled to the oscillator for comparing the testing clock signal and a predetermined clock frequency, then outputting a voltage controlling signal. The voltage adjusting circuit is coupled to the controlling circuit for adjusting the voltage value of the voltage signal according to the voltage controlling signal.
