Patent ID: 7835453

Claim:
A driver circuit for transmitting a differential logic signal over transmission lines comprising: a differential circuit having a first input coupled to a first data signal, a second input coupled to a second data signal, a first driver output with a first source resistance coupled to an input of a first transmission line and generating a first output signal, and a second driver output with a second source resistance coupled to an input of a second transmission line and generating a second output signal, wherein the first output signal is a difference between the first and second data signals amplified with a compensated gain, and the second output signal is a complement of the first output signal; a driver compensation network coupled to the differential circuit for setting the compensated gain to have a maximum gain value for frequencies greater than a first frequency, attenuating the maximum gain value of the differential circuit to a minimum gain value at frequencies below a second frequency substantially lower than the first frequency, and setting the compensated gain of the amplifier to transition between the minimum and maximum gain values at frequencies between the first and second frequencies, wherein a differential receiver comprises a receiver compensation network for setting the receiver gain of the differential receiver at a maximum gain value for frequencies greater than a first frequency, attenuating the maximum gain value to a minimum value at frequencies below a second frequency substantially lower than the first frequency, and setting the receiver gain to transition between the minimum and maximum values at frequencies between the first and second frequencies; and wherein an output of the first transmission line is coupled to a first receiver input of the differential receiver, an output of the second transmission line is coupled to a second receiver input of the differential receiver, and a differential termination resistance is coupled between the outputs of the first and second transmission lines, the differential receiver generating a detected signal at a receiver output as the difference between a received first signal at the first receiver input and a received second signal at the second receiver input amplified by a receiver gain.
