ABSTRACT:
A driver circuit is configured as a frequency compensated differential amplifier having one input coupled to a first data signal and a second input coupled to a second data signal. Each stage of the differential amplifier is biased with a current source. The driver circuit generates a first output signal coupled to the input of a first transmission line and a second output signal coupled to the input of a second transmission line. The first and second output signals are generated as the difference between the first and second data signals amplified by a compensated gain. A compensation network that attenuates the low frequency components of the input signals relative to the high frequency components is coupled between current sources biasing the differential amplifier. The outputs of the first and second transmission lines are coupled to the inputs of a differential receiver that may or may not be frequency compensated.
