Abstract
A duty cycle adjusting system includes a detection circuit, a first clock signal adjusting circuit connected with the detection circuit, and a second clock signal adjusting circuit connected with the detection circuit, wherein the detection circuit detects a duty cycle of a first output signal outputted by the first clock signal adjusting circuit and a duty cycle of a second output signal outputted by the second clock signal adjusting circuit, and outputs a first detection signal and a second detection signal, the first and second output signals are a pair of differential clock signals, the first and second detection signals are adapted for respectively adjusting rising edges of the pair of differential clock signals. No peripheral circuit is needed to provide the bias in the duty cycle adjusting system. The duty cycle adjusting system has the simple structure and can be independently applied to the clock path.
