Abstract
Apparatuses and methods for duty cycle error correction of clock signals are disclosed. An example method includes detecting a clock period error between a first clock signal and a third clock signal and adjusting a timing of the first or third clock signals based on the clock period error therebetween. The method further includes detecting a clock period error between a second clock signal and a fourth clock signal and adjusting a timing of the second or fourth clock signals based on the clock period error therebetween. Additionally, the example method includes detecting a duty cycle error between the first, second, third, and fourth clock signals, and adjusting a timing of the first and third or second and fourth clock signals based on the duty cycle error therebetween.
