Abstract :
Low voltage CMOS interface circuitry with self-correcting pull-up and pull-down output resistances to match the printed circuit board transmission line impedance, suitable for use in both series and parallel high-speed digital communication between integrated circuits and suitable for interfacing CMOS to heterogeneous logic (e.g. ECL), is described. The output driver impedance is controlled by the use of a pull-up and a pull-down, binary weighted transistor ladder in conjunction with an A-to-D convertor and an external resistor, representing the transmission line impedance
