Digitally tuneable on-chip resistor in CMOS for high-speed data transmission

A method of utilizing impedance control techniques using thermometer code circuit and an internal current source to create high speed data transmission transceiver is described in this paper. Since digital signals are the only inputs to these new impedance control circuits, on-chip dc power dissipation can be reduced. Eye pattern measurements show on-chip resistor has good performance in high-speed data transmission when compared to off-chip resistor.
