Abstract
A method for manufacturing a bus having enhanced signals qualities which includes the steps of determining the intrinsic inductance per unit length (L.sub.0) and intrinsic capacitance per unit length (C.sub.0) of the unloaded bus. The method also includes the step of determining the load capacitance per unit length (C.sub.d) of the bus that is attributable to the peripheral devices that will be attached to the bus. Based on these values, an adjustment inductance (L.sub.d) per unit length for the bus is calculated for the bus with L.sub.d being substantially equal to L.sub.0 * C.sub.d /C.sub.0. Finally, one inductor of value L.sub.d is added per unit length of the bus. The added adjustment inductance offsets the capacitance attributable to the peripheral devices attached to the bus. The result is that signals within the bus have rise and fall times acceptable for high speed operation.
