Device and method for inhibiting power fluctuation |
摘要 |
A power fluctuation inhibiting device for effectively inhibiting fluctuation of power supply voltage that is supplied to internal circuits. The inhibiting device includes a power fluctuation measuring circuit for measuring peaks in the fluctuation of the power supply voltage produced when the internal circuits are operated. A clock signal control circuit adjusts phases of clock signals provided to respective ones of the internal circuits in accordance to the peak measuring result to substantially offset the fluctuation peaks produced when the internal circuits are operated.
