MODULATION PROFILE GENERATOR WHICH CREATES AN IDEAL MODULATION PROFILE CAPABLE OF EFFECTIVELY REDUCING ELECTROMAGNETIC DISTURBANCE AND A SPREAD SPECTRUM CLOCK GENERATOR INCLUDING THE SAME

摘要

PURPOSE: A modulation profile generator and a spread spectrum clock generator including the same are provided to effectively reduce electro-magnetic disturbance by creating a modulation profile which is similar with the form of an ideal Hershey-kiss profile.;CONSTITUTION: An input signal generating part(101) creates an input signal for the formation of a modulation profile. A function calculation part(103) produces the result of a square root graph type by calculating a function about the input signal. A profile production part(105) creates a nonlinear modulation profile using a function calculation result. A coefficient control part(107) determines a form of the nonlinear modulation profile by controlling coefficient of the function in the function computational process. The input signal generating part is formed into a comptometer structure capable of generally changing a number.;COPYRIGHT KIPO 2012
