Abstract
A clamping circuit 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. An impedance path is defined between each of the chips and the power supply to define a current path for switching noise through the top of the module. A high impedance path is defined for voltages below a predetermined upper limit of the chip supply voltage and a low impedance path is defined by the clamping circuit for the voltage range where noise superimposed on the chip supply voltage occurs.
