5.16 Show thatwhen channel-lengthmodulation is neglected (i.e., λ = 0), plotting iD/kn versus vDS for various values of vOV, and plotting iD/kn versus vOV for vDS ≥ vOV, results in universal representation of the iD−vDS and iD−vGS characteristics of the NMOS transistor. That is, the resulting graphs are both technology and device independent. Furthermore, these graphs apply equally well to the PMOS transistor by a simple relabeling of variables. (How?) What is the slope at vDS = 0 of each of the i D/kn versus vDS graphs? For the iD/kn versus v OV graph, find the slope at a point vOV = VOV.
