摘要：PROBLEM TO BE SOLVED: To provide a transmitter of a semiconductor device, and to provide a method of transmitting signals thereof. SOLUTION: The transmitter of a semiconductor device is provided with a pre-driver stage, a main driver stage, and a control circuit. The pre-driver stage modifies a common-mode level and the amplitudes of first internal output signals to generate second internal output signals in response to first driver control signals and first termination control signals. The main driver stage modifies the common mode level and the amplitude of the second internal output signals to output signals, in response to second driver control signals and second termination control signals. The control circuit detects the common mode level and the amplitude of input signals that correspond to the output signals, and generates the first and second driver control signals and the first and second termination control signals. The common mode level and the amplitude of the output signals are the same as those of the input signals. The transmitter of the semiconductor device can output output signals that correspond to input signals, having various common-mode levels and amplitudes. COPYRIGHT: (C)2006,JPO&NCIPI
