WebBSIM4 Output Resistance and Early Voltage Variations Early voltage can only be varied for intermediate channel lengths (e.g. 3·L nom) with BSIM4! Such gds-deviations (inside above blue circles) have been adjusted using effect of DITS parameters on Rout. BSIM3v3 is only sensitive for early voltage variations at short channel
