WebVT0 = the threshold voltage with VSB =0 i.e. with out the body effect. Depletion mode Versus Enhancement mode MOSFET: • If a MOSFET is on (i.e. in strong inversion) at zero bias then it is a depletion Mode MOSFET (it is normally ON). o We actually have to apply a VGS < Vth to turn off the NMOS or a VGS > Vth for PMOS . WebFirst observation: Vth is not accurately specified as you can see in the datasheet; this because the threshold voltage is depending heavily from …
