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.

Claim (Index 7):
A skew compensation circuit comprising:\n a rectifier configured to generate a rectified voltage of which a variation in an external voltage is compensated for by rectifying the external voltage; a skew detection circuit configured to generate a first skew detection signal and a second skew detection signal using the rectified voltage by detecting threshold voltage characteristics of an NMOS transistor and a PMOS transistor; a skew compensation signal generation circuit configured to generate a skew compensation signal by comparing the first and second skew detection signals and a plurality of reference voltages; a variable delay circuit configured to generate a compensation signal by delaying an input signal for a delay time varied according to the skew compensation signal; and a reference voltage generation circuit configured to select partially divided voltages corresponding to a current temperature among a plurality of divided voltages generated using the rectified voltage and output the selected divided voltages as the plurality of reference voltages.
