ABSTRACT:
A frequency adjusting circuit for a central processing unit (CPU) includes a transforming unit for transforming a change of a current signal of the CPU into a voltage signal, an amplifying unit for amplifying the voltage signal from the transforming unit, a switching unit being turned on or turned off by the amplified voltage signal from the amplifying unit, and a basic input/output chip for regulating a frequency of the CPU through a clock generator.
