Webconnected to a constant voltage, it is the same things as being connected to the small signal ground. Rule #1 Gate Resistance The resistance “looking” into the gate of a MOSFET transistor (NMOS or PMOS) with the gate being at small-signal ground is infinite because one is essentially looking into the gate capacitor. Rule #2 Drain Resistance Webmaintain a reverse bias across the diode present between the source and the drain terminals. Similarly, an N-channel MOSFET with its body connected to the most negative potential (Figure 6) in the circuit can support BPS function.

The length, therefore, the resistance of the epi layer is a function of the voltage rating of the device as high voltage MOSFETs require thicker epitaxial layer. WebHeavier doping and less thickness provide a lower voltage drop. However, as a diode, the maximum voltage the MOSFET can block with the switch open while acting like a reverse-biased diode is limited by the doping level and thickness of the device. Boosting the doping to reduce the resistance leads to a reduced ability to block voltage.
