ABSTRACT:
An input signal receiver of a semiconductor device includes a gain control unit for outputting a gain control signal and a variable gain amplifier for amplifying external clock in response to the gain control signal, wherein the gain control signal determines a gain of the variable gain amplifier. Further, the input signal receiver includes a buffer whose input terminal is connected to an output terminal of the variable gain amplifier and output terminal is connected to another element of the semiconductor device.
