Early voltage And intrinsic resistance in Cadence
i am having problems in finding out the early voltage through graph !!!! i dont know what function to give in the calculator in cadence to find the exact value of early voltage !!!!!! Please if any one can give me an intuitive explanation of how to extrapolate the Id vs Vds graph to find the point at which the line cuts the xaxis to find Va

Re: Early voltage And intrinsic resistance in Cadence
With C@dence' ADE calculator (use the derivative function) identify gds at your selected bias point, then calculate the Early voltage VA from the equation given in the figure below:
