Abstract
A skew compensation circuit includes a skew detection circuit configured to generate skew detection signals by detecting a skew characteristic of a basic logic element constituting a semiconductor apparatus, a skew compensation signal generation circuit configured to generate a skew compensation signal by comparing the skew detection signals and a plurality of reference voltages, a variable delay circuit configured to generate a compensation signal by delaying an input signal by a delay time varied according to the skew compensation signal, and a reference voltage generation circuit configured to generate the plurality of reference voltages of which offset components are compensated for according to variations of a temperature and an external voltage.
