    摘要: There is provided a modulation profile generator and spread spectrum clock generator including the modulation profile generator. The modulation profile generator includes an input signal generator that generates an input signal; a function calculator that outputs a function calculation result in the form of a square root graph by using the input signal as an input of a function; and a profile generator that generates a non-linear modulation profile based on the function calculation result. As a result, it is possible to effectively reduce electromagnetic interference.
