Using a circuit that is the complement of the one in Fig. 5.35, draw the schematic for the bottom error amplifier and output transistor M₂, which are shown in block diagram form in Fig. 5.32. In the error amplifier, label the transistors as M₂₁-M₂₇, where M₂₁is the complement of M₁₁, M₂₂is the complement of M₁₂, etc. Also, label the current sources complementary to I_BIASand I_TAILas I_BIASPand I_TAILP, respectively.
