Abstract: An exemplary circuit board includes a power plane with a first metal plate, a ground plane with a second metal plate, a channel etched in one of the metal plates to define an isolated area therein, and a coupling circuit. A gap is formed between the isolated area and other area of the one of the metal plates. The coupling circuit is electronically connected between the first and the second metal plates in the isolated area for reducing a resonance frequency caused by the channel. The circuit board can reduce electromagnetic interference generated therein.

Abstract: A controlling circuit for automatically adjusting clock frequency of a CPU is provided. The controlling circuit includes: a current sensing circuit for converting a current signal of the CPU to a voltage signal; a voltage amplifying circuit for amplifying the voltage signal; a multi-stage switching circuit for converting the amplified voltage signal to switched signals; and a priority decoding circuit decoding the switched signals, the decoded switched signals being input to a clock generator of the CPU, and thereby adjusting the clock frequency of the CPU to fit different load on the CPU.
