Abstract
A duty compensation device of one embodiment has a structure capable of more accurately setting a duty of a clock within an appropriate range. The duty compensation device comprises a duty adjusting unit, a duty measuring unit, a controlling unit. The duty measuring unit generates a sampling clock of a frequency fthat is asynchronous to the clock over an n-th period T(n=1 to N and N is an integer of 3 or more), and obtains measurement information for specifying the duty of the clock by using the sampling clock. The controlling unit determines a control code to be given to the duty adjusting unit based on control code candidates obtained for each of the N periods Tto Tand the control code candidates in which the duty specified by measurement information obtained by the duty measuring unit is within a predetermined range.
