Calculate the common-mode input range of the op amp in Fig. 6.25. Assume that all the transistors are enhancement-mode devices with |V_t| = 1V,and ignore the body effect. Also assume that the biasing is arranged so that |V_ov|=0.2 V for each transistor except M₉. Finally, assume that M₁and M₂are biased at the edge of the active region by M₉and I_C.
