Patent ID: 7324032

Claim:
A method of matching dynamic elements, the method comprising: sequentially selecting at least one first unit element 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 least significant bit (LSB) of the first digital data when the reference unit element is selected; sequentially selecting at least one second unit element corresponding to a value of second digital data among the M unit elements in a second direction when the value of the LSB of the first digital data is a first value, the second direction being opposite to the first direction, the second digital data being inputted next to the first digital data; and sequentially selecting the at least one second unit element in the first direction when the value of the LSB of the first digital data is a second value.
