Abstract:
1. A differential data transferring system for transferring first, second, and reference transfer data signals through first and second transfer line sets to generate first, second, and reference output data signals, in which the first transfer line set comprises a first plus transfer line and a first minus transfer line and the second transfer line set comprises a second plus transfer line and a second minus transfer line, the differential data transferring system comprising: a data transmitting portion operative to selectively couple one of the first plus transfer line and the first minus transfer line to a first middle voltage level and selectively couple the other of the first plus transfer line and the first minus transfer line to one of a first high voltage and a first low voltage according to the first transfer data signal and the reference transfer data signal, the data transmitting portion operative to selectively couple one of the second plus transfer line and the second minus transfer line to a second middle voltage level and selectively couple the other of the second plus transfer line and the second minus transfer line to one of a second high voltage and a second low voltage according to the second transfer data signal and the reference transfer data signal, wherein the first middle voltage is between the first high voltage and the first low voltage, and wherein the second middle voltage is between the second high voltage and the second low voltage; and a data receiving portion operative to generate the first, second, and reference output data signals, wherein the first output data signal depends on the voltage levels in the first plus transfer line and the first minus transfer line, the second output data signal depends on the voltage levels in the second plus transfer line and the second minus transfer line, and the reference output data signal depends on a first dividing voltage and a second dividing voltage, and wherein the first dividing voltage is generated by dividing the voltages between the first plus transfer line and the first minus transfer line, and the second dividing voltage is generated by dividing the voltages between the second plus transfer line and the second minus transfer line.
