摘要：A driver circuit is configured as a frequency compensated differential amplifierhaving one input coupled to a first data signal and a second input coupled to a seconddata 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 transmissionline and a second output signal coupled to the input of a second transmission line. Thefirst and second output signals are generated as the difference between the first andsecond data signals amplified by a compensated gain. A compensation network thatattenuates the low frequency components of the input signals relative to the highfrequency components is coupled between current sources biasing the differentialamplifier. The outputs of the first and second transmission lines are coupled to the inputsof a differential receiver that may or may not be frequency compensated.
