Abstract: A signal transmitter includes a plurality of driver slices. Each of the driver slices includes a driving circuit, a plurality of first transistors, and a plurality of second transistors. The driving circuit receives an input signal and outputting an output signal. The first transistors provide a first impedance according to signals on gate terminals of the first transistors. The second transistors provide a second impedance according to signals on gate terminals of the second transistors. Each of the gate terminals of the first transistors and the second transistors is selectively coupled to a bias voltage which controls the corresponding first transistor or second transistor to operate in a triode region, or coupled to a predetermined voltage which controls the corresponding first transistor or second transistor to behave as a switch.

Abstract: A voltage mode transmitter includes a first output terminal, a second output terminal, and a plurality switch-resistor units between the first output terminal and a first voltage source, between the second output terminal and the first voltage source, between the first output terminal and a second voltage source, and between the second output terminal and the second voltage source. Each switch-resistor unit includes a switch and a resistor connected in series. The switches of the switch-resistor units are controlled such that a common-mode voltage of a differential signal outputted at the first and second output terminals deviates from an average of voltages provided by the first and second voltage sources.
