| 发明名称 | Spread-spectrum apparatus for voltage regulator | ||
| 摘要 | Described is an apparatus for providing spread-spectrum to a clock signal. The apparatus comprises: an oscillator to generate an output clock signal, the oscillator to receive an adjustable reference signal to adjust frequency of the output clock signal; a first circuit to provide a first signal indicative of a center frequency of the output clock signal; a second circuit to generate a switching waveform to provide spread-spectrum for the output clock signal; and a third circuit, coupled to the first and second circuits, to provide the adjustable reference signal according to the first signal and the switching waveform. | ||

| 主权项 | 1. An apparatus comprising: an oscillator to generate an output clock signal, the oscillator to receive an adjustable reference signal to adjust frequency of the output clock signal; a first circuit to provide a first signal indicative of a center frequency of the output clock signal; a second circuit to generate a switching waveform to provide spread-spectrum for the output clock signal; and a third circuit, coupled to the first and second circuits, to provide the adjustable reference signal according to the first signal and the switching waveform, wherein the second circuit comprises: an up-down counter operating at a reference clock frequency; and a first digital to analog converter (DAC) coupled to the up-down counter, the first DAC to generate the switching waveform. | ||
