Quantitative skew sensor

A skew sensor comprising at least two skew detectors,

• wherein each skew detector detects a skew between two input signals,
• wherein a first skew detector receives either a first clock signal or a second clock signal as a first input signal and the other one of the first clock signal and the second clock signal delayed by a first delay difference induced by one or more delay elements as a second input signal,
• wherein a second skew detector receives either the first clock signal or the second clock signal as the first input signal and the other one of the first clock signal and the second clock signal optionally delayed by a second delay difference induced by one more delay elements, wherein the second delay difference is different from the first delay difference, as the second input signal, and
• wherein a skew control unit measures a skew between the first clock signal and the second clock signal comprises using the skew sensor.
