The present invention discloses a parameter generating device and the method thereof to generate a parameter for circuit operation in which the parameter corresponds to an N degree polynomial of a characteristic curve while said N is a positive integer. The parameter generating device comprises: a storage circuit to store at least N+1 initial values that are determined by a start value and a unit variation amount; and a parameter calculating circuit, coupled to the storage circuit, to carry out addition calculation for at least [(K&#x2212;1)&#xd7;N+1] time(s) if a multiple K is positive or subtraction calculation for at least &#x2212;K&#xd7;N time(s) if the multiple K is negative, so as to generate the aforementioned parameter, wherein the multiple K is derived from a difference divided by the unit variation amount while the difference is a current value minus the start value.
