A new methodology for active substrate parasitic extraction in automotive HV-CMOS processes

Published: Mar 2019

A Re-design root cause in Smart Power ICs, like motor drivers. Some customers are affected by Re-designs due to unwanted substrate coupling, Today these problems are handled by hand, Trial & Error by very experienced designers after measured silicon: time consuming. Substrate coupling is an active and distributed large signal problem. Not locally concentrated. AC simplifications do not work.
