Current mode logic buffer device for suppressing electromagnetic interference and signal generating method thereof

Abstract

A current mode logic buffer device for suppressing electromagnetic interference includes two output ports and three or more sets of current mode logic buffers. First, second, and third current mode logic buffers respectively generate first, second, and third clock signals in response to first, second, and third differential input signals. The second differential input signal is delayed by a time difference from the first differential input signal, and the third differential input signal is delayed by the time difference from the second differential input signal. The output ports receive the first clock signal, the second clock signal, and the third clock signal, and output a full clock signal. A signal generating method for suppressing electromagnetic interference is also provided.
