A skew detection circuit may include a bias circuit configured to generate a first bias signal and a second bias signal, a reference voltage circuit configured to generate a third bias signal and a fourth bias signal, and a detection circuit configured to generate, using the first to fourth bias signals, a plurality of skew detection signals. The skew detection signals may correspond to effects of one or more of process variations, voltage variations, and temperature variations.
