Abstract
A method for determining bit element values for an impedance control circuit is provided which controls the output impedance of drivers which are coupled to the impedance control circuit. Accordingly, a desired driver output impedance can advantageously be established and maintained over a wide range of variations in operating conditions and manufacturing processes. Thereby shortening the signal settling time and increasing the attainable signaling frequency.
