Abstract

Switching of power stages in smart power ICs, which drive an inductive load, turns on parasitic bipolar transistors and inject minority carriers into the substrate, which can affect the functionality of the chip. We present a new parasitic transistor model for post layout simulation, which accounts for a strongly inhomogeneous current flow, a base width of up to a few hundred μm, multiple base contacts and collectors, and whose parameters are easily extractable from layout and technology data.
