Abstract
A semiconductor apparatus includes a first clock path which generates a first output clock signal by delaying a first phase clock signal, and a second clock path which generates a second output clock signal by delaying a second phase clock signal based on a delay compensation signal. The oscillating path generation circuit forms oscillating paths with the first clock path and the second clock path. The delay information generation circuit generates a delay compensation signal based on oscillating signals generated by forming the oscillating paths.
