ABSTRACT:
A duty cycle corrector, including a first, second circuit and a third circuit is disclosed. The third circuit is configured to obtain a threshold value in response to charge flow that is regulated by the first circuit and the second circuit, wherein the first circuit is configured to receive a clock signal and change the charge flow at a first transition of the clock signal. The second circuit is configured to change the charge flow at a second transition of the clock signal. The first circuit and the second circuit are configured to change the charge flow in response to obtaining the threshold value.
