Abstract: Examples describe a duty cycle correction circuit for correcting duty cycle distortion from memory. One example is an integrated circuit for correcting an input clock signal. The integrated circuit includes a first leg circuit and a second leg circuit. The first leg circuit and the second leg circuit both comprise a charging circuit and a discharging circuit. Each charging circuit comprises a first plurality of transistors and each discharging circuit comprises a second plurality of transistors. The charging circuit is coupled to the discharging circuit in series. A number of transistors of the first plurality of transistors in the first leg circuit is different from a number of transistors of the first plurality of transistors in the second leg circuit.
