Abstract
A duty correction device may be provided. The duty correction device may include a duty controller configured to output a control signal by controlling a duty of a duty corrected signal, and detect a level of a feedback signal to convert the duty based on a code signal which is applied at a section where the level of the feedback signal corresponds to a logic level. The duty correction device may include a power gating circuit configured to generate the feedback signal by driving the control signal.
