ResistanceNumerical analysisSemiconductorsTransistorsWe derived the equation for the drain current of a short-channel MOSFET with nonzero differential conductance in saturation regime describing its nonlinear dependence on "extrinsic" drain bias and accounting for the parasitic and contact series resistances. ...
(0.0199mils=0.506mm) normalized wire resistance. (32.37?/1000ft =0.1062m?/mm) m? = 21.2m? mm The DC winding resistance is: R W,DC = N P ? MLT ? ρ W R W,DC = 8 ? 24.9mm ? 0.1062 Next, check the AC resistance based on Dowell’s curves according to the following steps: ...
Furthermore, on-state resistance is not equal to the resistance expressed by the triode-region equation given above. The latter is the resistance of the MOSFET’s channel, whereas on-state resistance encompasses other sources of resistance—bond wires, the epitaxial layer, etc. Resistance characte...
