Abstract
A duty cycle corrector comprising a first circuit and a second circuit. The first circuit is configured to receive a clock signal having a first phase and a second phase and to obtain a first threshold value based on the length of the first phase and part of the second phase and provide a first pulse and response to the first threshold value. The second circuit is configured to receive the clock signal and to obtain a second threshold value based on the length of the second phase and part of the first phase and provide a second pulse in response to the second threshold value. The time between the start of the first pulse and the start of the second pulse is substantially one half clock cycle.
