WebFigure 2 illustrates a simplified cross section showing two CMOS structures, one PMOS and one NMOS; these could be connected together as an inverter or as the switch channel. The parasitic transistors responsible for latch-up behavior, Q1 (vertical PNP) and Q2 (lateral NPN) are also shown. Figure 2. Webmechanism of the parasitic switch-on lies in the capacitive voltage divider between drain-to-source and gate-to-source voltage. Fig. 1.shows a basic half-bridge configuration, being a part of an H-bridge or a three-phase bridge. If the upper MOSFET is switched on, the lower one has to be switched off in order to avoid a shoot-though and
