Patent ID: 7154307

Claim:
A current mode transfer logic transmission line driver system comprising: a transmission line, defining at least a first and a second signal carrying conductor, the transmission line defining a characteristic impedance; with the transfer logic in one logic state, means for selectively driving unequal signal currents through the first and the second signal carrying conductors, respectively, wherein the difference current, between the unequal signal currents, flows back to the means for selectively driving; a terminating resistor connected between the distal ends of the first and the second signal carrying conductors, wherein no common mode signals are introduced into or measured along the terminating resistor; means for receiving the unequal signal currents at the distal end of the transmission line; and means for sensing the unequal currents, and wherein a logic state is defined by which of the two conductors carries the larger of the unequal currents.
