WebAs you well know, a basic n-channel MOSFET ( Figure2) consists of two heavily-doped n-type regions, the source and drain, that comprise the main terminals of the device. The gate was made of metal in early incarnations, but is now made of heavily doped polysili-con, while the bulk of the device is p-type and is typically rather lightly doped. WebEarly versions of MOSFETs were very susceptible to volt-age breakdown due to voltage transients and also had a tendency to turn on under high rates of rise of drain-to-source voltage (dV/dt), both resulting in catastrophic fail-ures. The dV/dt turn-on was due to the inherent parasitic NPN transistor incorporated within the MOSFET, shown
