ABSTRACT:
A method of matching dynamic elements includes sequentially selecting first unit elements corresponding to a value of first digital data among M unit elements in a first direction, the M unit elements being for converting sequentially inputted digital data to an analog signal; checking whether a reference unit element is selected; checking a value of a LSB of the first digital data when the reference unit element is selected; sequentially selecting second unit elements corresponding to a value of second digital data inputted next to the first digital data among the M unit elements in a second direction opposite to the first direction when the value of the LSB of the first digital data is a first value; and sequentially selecting the second unit elements in the first direction when the value of the LSB of the first digital data is a second value.
