Abstract

According to one or more embodiments, a skew control circuit for controlling the skew between at least two digital signals is provided. The skew control circuit may include a pulse generator that may generate a pulse with a pulse width, whereby the pulse width of the pulse may depend on a skew between edges of the two digital signals. The skew control circuit may also include a pulse width sensor that may output a pulse width value that represents the pulse width of the generated pulse. The skew control circuit may further include a skew controller that may adjust a delay of the at least one of the digital signals based on a target skew value and the pulse width value.
