Abstract
Compensation circuit means for inclusion in an off-chip driver circuit is provided to reduce self-induced switching noise in a multi-chip module semiconductor structure. A module section interconnects the chips and the chips have a power supply and power leads respectively. The compensation circuit means, which is coupled across the output transistor circuit of the off-chip driver, may comprise one or more serially connected diodes. The diode (or diodes) may be formed by the base collector junction of a bipolar transistor.
