The Inverting Amplifier 2 v is the node voltage at the reference node (ground), so 2 0 v = . The op amp is ideal so 12 vv = . (All op amps are ideal in this course.) Consequently, 0 = = Apply KCL at the node connected to the inverting input of the op amp to get s1 1o s o f if i f i 4 v v R iv RR R R R −− =+ = = = s s v v Beware: Both of si vR =− and o = f are sometimes called the “gain” of the inverting amplifier.
