First Claim
Patent Images
1. An apparatus for correcting duty cycle, the apparatus configured to correct a duty ratio of an input signal, the apparatus comprising:
- an alert clock configured to adjust a signal width of the input signal;
a first equalization unit configured to equalize a width of an output signal of the alert clock;
an inverter configured to reverse the output signal of the alert clock;
a second equalization unit configured to equalize a width of an output signal of the inverter; and
a comparator configured to compare the output signals of the first and second equalization units, and output a difference between the output signals of the first and second equalization units.
