Question
( 5 0 pts ) : For the circuit of Fig . 2 , your task is to find how the output voltage V o u t depends on the inputs V 1 and V 2 in this cascaded ( serial ) connection of two Op . Amp. circuits. Here, you can assume that Op . Amps. are ideal and are operating in the linear mode. a . i ) ( 1 5 pts ) Find V o u t ( output of the first stage ) in terms of V 1 . ii ) ( 5 pts ) Is the output voltage V o u t 1 ( output of the first stage ) affected by the presence of the second stage? Explain your answer. iii ) ( 1 0 pts ) Find the input resistance as seen by V 1 . b . i ) ( 5 pts ) Find the input resistance as seen by V 2 . ii ) ( 1 5 pts ) Find V o u t in terms of V 1 and V 2 . 1 of 2 Fig. 2
