2 Circuit Example R. Dutton, B. Murmann 3 EE114 (HO #30) What is the loop gain in this circuit? Return Ratio Analysis As we've in previous lectures such a hand calculation is pretty () t r i i s T = R. Dutton, B. Murmann 4 EE114 (HO #30) As we ve in previous lectures, such a hand calculation is pretty straightforward How can we simulate T(j ω ) in Spice?
