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.

Abstract: A bus line is provided with broadly distributed signal termination by using switched termination logic where the pull up resistance of a driver corresponds to the characteristic impedance of the line and the pull down resistance of the driver corresponds to the number of drivers coupled to the line. Accordingly, signals being transmitted over the bus suffer relatively few reflections thus advantageously producing a shortened signal settling time, thereby increasing the attainable signaling frequency.

Abstract: A receiver is provided which quickly and efficiently recognizes signals by including with the receiver a resolving circuit which is coupled to a node control circuit which determines the signals to be recognized. The resolving circuit can operate with supply voltage levels as low as one threshold voltage. Also, the signal hold time can be made very small depending on the sizing of certain transistors. Other advantages include reduced power consumption, high speed operation, good rejection of input noise and power supply noise, ability to resolve small (e.g., 1.0 mVolt) voltage differences, and the ability to function with a variety of types of drivers, including HSTL, DTL and PECL.
