Abstract:
1. A device, comprising: a first conductor and a second conductor configured to form a differential transmission line to transmit an electrical signal; and a plurality of leakage resistors connected between the first and second conductors at different positions along the differential transmission line to make a phase velocity and a signal attenuation of the electrical signal to be independent of a frequency of the electrical signal; wherein the device further includes a signal driver coupled to one end of the differential transmission line to generate the electrical signal and a signal receiver coupled to another end of the differential transmission line to receive the electrical signal, and the plurality of leakage resistors are connected to the differential transmission line between the signal driver and the signal receiver, wherein the plurality of leakage resistors are equal in resistance, wherein each leakage resistor has a conductance per one unit length of RC/L, where R, C and L are effective resistance, capacitance and inductance of the differential transmission line per one unit length, respectively, wherein the plurality of leakage resistors are equally spaced from one another along the differential transmission line, and wherein a spacing between two adjacent leakage resistors is equal to or less than ct
