Abstract
A phase splitter is disclosed for preventing a timing loss from a presentation timing mismatch of a clock signal of a phase equal to a reference signal and a clock signal of a phase inverted from the reference signal, including a semiconductor device for providing a signal of the same phase and a signal of an inverted phase with respect to a received reference signal, the semiconductor device including a first and a second transmission gates for receiving the reference signal and an inverted version of the received reference signal, and a third and a fourth transmission gates for receiving the reference sign, and the inverted version of that reference signal and for generating a signal having the same phase as the received reference signal and for providing that signal at the same time that the first and second transmission gates provide their output signal, the signals output by the first and second transmission gates having the same timing and opposite phase as the signal output by the third and fourth transmission gates with respect to the reference signal.
