Question: For the three-stage op amp with nested Miller compensation in Fig. 9.30c, determine the values of the compensation capacitors that give a 60¦ phase margin

For the three-stage op amp with nested Miller compensation in Fig. 9.30c, determine the values of the compensation capacitors that give a 60—¦ phase margin when the op amp is in a unity-gain negative feedback loop (f=1). Assume that the zeros due to feed forward have been eliminated. Design for complex poles p₂and p₃. Use R₀= R₁= R₂= 5 kÎ©, C₀= C₁= 0.5 pF, and C₂= 6 pF. Use g_m0= g_m1and g_m2= 6_gm1.
