Assume both op-amps are ideal and their input/output voltages are ei, e and eo, as shown in the Figure. Using the impedance approach: obtain the transfer function for each op-amp, i.e. E(s)/E:(s) and E(s)/E(s). (i) (ii) hence obtain the complete transfer function for the system, i.e. E(s)/Ei(s). (iii) Determine D(s) = E.(s)/E:(s) when RI = R2 = R3 R4 12 and Ci =1 F, C2 2 F. (b) Consider the closed-loop control system shown in Figure Qlb. Σ K.D(s) (s+2) Figure Qlb K is the gain and D(s) is the transfer function obtained in part (a)-iii. (i) Plot open loop zeros and poles for the above system in the s-plane. ". Determine whether the point (-1+j) is a closed loop pole for any value of K, by considering the angle criterion at this point. (ii)
