Abstract
A duty correction circuit includes a clock buffer configured to buffer an input clock and generate a buffer clock, a swing level conversion block configured to generate an internal clock, which transitions to levels of a sync voltage and a power supply voltage, in response to a voltage level of the buffer clock, a duty control block configured to generate duty information and frequency information by using a high pulse width and a low pulse width of the internal clock, and a current control block configured to control a time point, at which a logic value of the buffer clock transitions, in response to the duty information and the frequency information. The current control block includes a plurality of first current paths coupled in parallel to one another in order to control the time point at which the logic value of the buffer clock transitions.
