Crosstalk and Common Mode Aspects of Differential Line Driver and Receiver Circuits

Modern systems increasingly require the high speed transmission of digital data between subsystems. To minimize the worst effects of crosstalk, electro­ magnetic field pickup, and common mode interference, balanced differential circuits are commonly utilized in this application. Some of the trade-offs available to the designer of these, circuits are discussed, using the complimentary techniques of computerized modelling and experimental measurements.
