The single-stage op amp in Fig. 9.54 has a 45° phase margin when the op amp is in a unity-gain negative feedback loop (f=1) with an output load capacitance C_L=2 pF. What value of C_Lwill give a 60° phase margin? (Assume that the capacitance at the op-amp output is dominated by C_Land the op-amp gain a_Ï…(s) can be modeled as having two poles.)
