Homework 26 ECE201: Linear Circuit Analysis Due in class: Wednesday, November 2, 2011 1. For the ideal operation amplifier shown below, determine the following. a. What are the numerical values for i 2 and i - ? b. In terms of the sources and resistances, what are the voltages at the inverting V - and non- inverting V + terminals of the ideal opamp? c. If V 2 = 0V, V 1 = 30, R 1 = 2 , and R f = 1 , find V out . d. If V 2 = 10V, V 1 = 30, R 1 = 2 , and R f = 1 , find V out . e. If V 2 = 10V, V 1 = 30, R 1 = 2 , and R f = (1/2) , find V out . f. If V 2 = 10V, V 1 = 30, R 1 = 2 , and R f = 10 , find i oa . g. If V 2 = 30V, V 1 = 10, R 1 = 2 , and R f = 10 , find i oa . h. Gain is defined as V out /V in . What does R f need to be such that the gain of the opamp has a magnitude of 1000? Assume that V in = V 1 , R 1 = 2 , and V 2 = 0V. i. If V 1 = V 2 = 10V, then what is V out and i oa ? j.
