The voltage transfer curve of an inverter is given in Fig. 6--46. The threshold volt ages of the NFET and PFET are -+0.4 and -0.4 V. respectively. Determine the states of the two transistors (cut-of llinear. or saturation) at points A. B. C. and D. respeetively. (Assume the output conductance of the transistor is very large.)
