Duty cycle correcting circuit and method of correcting a duty cycle |
摘要 |
A duty cycle correcting circuit includes a duty ratio control unit configured to alternately change logical values of a plurality of bits of a pull-up control signal and a plurality of bits of a pull-down control signal in response to a duty ratio detection signal, a duty ratio correcting unit configured to adjust driving abilities of a first driver and a second driver in response to the plurality of bits of the pull-up control signal and the plurality of bits of the pull-down control signal to output a correction clock signal, and a duty ratio detecting unit configured to detect a duty ratio of the correction clock to generate the duty ratio detection signal. |
