Shown in Fig. P7.71 is a popular scheme for synthesizing the compensation resistance Rc. This is simply the channel resistance of M9, in turn biased by the current source M10 and the diode-connected pair M11 and M12. (a) If this scheme is used in the PSpice circuit of Example 7.37, specify suitable WyL ratios for M9 through and M12 to implement the resistance Rc 5 1.07 kV under the constraint ID10 5 50 A. Hence, run a PSpice simulation, compare and comment. (b) Repeat, but for Example 7.38.
