early voltage
i have done extrapolating the Id versus Vds curves (shown in the attached file) to get the early voltage. But unfortunately i have got no early voltage. the data of Id,Vds,Vgs have been extracted from HSPICE simulation. Then i have done the extrapolation by MATLAB. But the curves do not intersect at any single point to produce the early voltage. please help me. if it is not possible to get the early voltage by extrapolation, please help me telling the way of getting the early voltage.
if i predict second order dependence of Id on Vds rather than a linear relationship in saturation the extrapolation becomes
but it is not satisfactory. please help me. thanking in advance.
