Consider the folded-cascode op amp of Fig. 12.8 when loaded with a 10-pF capacitance. What shouldthe bias current I be to obtain a slew rate of at least 10 ? If the input-stage transistors are operated at overdrive voltages of 0.2 V, what is the unity-gain bandwidth realized? If the two nondominant poles have the same frequency of 25 MHz, what is the phase margin obtained? If it is required to have a phase margin of 75, what must ft be reduced to? By what amount should CL be increased? What is the new value of SR?
