Systems, methods, and devices are provided for calibrating and correcting a clock duty cycle. An integrated circuit may include a clock tree that provides a clock signal and a circuit that is sensitive to clock duty cycle that receives the clock signal at a lower level of the clock tree. A first duty cycle correction circuit may adjust a clock duty cycle of the clock signal to a first target duty cycle at a higher level of the clock tree. A second duty cycle correction circuit may adjust a clock duty cycle of the clock signal to a second target duty cycle at the lower level of the clock tree.
