Abstract
An A/D converterincludes a front stage A/D conversion unit () including a first A/D conversion unit () that receives an analog signal from a CMOS image sensor () and generates a first digital value (D) and a first residual analog signal (V) through a folding integration A/D conversion operation, and a second A/D conversion unit () that receives a first residual analog signal (V) from the first A/D conversion unit () and generates a second digital value (D) and a second residual analog signal (V) through a cyclic A/D conversion operation, and a rear stage A/D conversion unit () that receives the second residual analog signal (V) from the front stage A/D conversion unit () and generates a third digital value (D) through an acyclic A/D conversion operation.
