Abstract

In LSI and VLSI (very large-scale integration) we are constantly increasing the number of internal circuits and external drivers on a chip. A necessary condition is to switch mode and more drivers simultaneously, which creates Delta-I noise (V = L /di//dt). The Delta-I noise is developed across a common node inductance (L) in the power supply path. To prevent supply path. To prevent a receiver on the active chip from false switching, this noise must not exceed the technology noise tolerance. Therefore, the number of simultaneously switching drivers must be limited.
