Abstract
A semiconductor apparatus includes an internal clock generation circuit, a receiver, and a sampling circuit. The internal clock generation circuit generates a receiving clock signal and a sampling clock signal based on a reference clock signal, the sampling clock signal having a phase different from the receiving clock signal. The receiver receives an input signal in synchronization with the receiving clock signal and to generate an amplified signal. The sampling circuit samples the amplified signal in synchronization with the sampling clock signal to generate an output signal.
