Exam #2 - Prob. #4 Solutions 1 4a. Find the equation for Vo in terms of Vin for the amplifier circuit below. (10 pts ) (assume ideal properties for the Op-Amp & the rules when there is feedback at the inverting terminal) 4b. If VIN = 2V, solve for Vo. ( 5 pts ) 4c. Determine the gain of the amplifier circuit below. ( 5 pts ) 2 k92 M If you simulate 1 ks 2 this circuit for M extra credit note VIN the polarity on the OpAmp inputs +10V V 1 I O 1 -10V + V Vo w 1 k 2 1 k2 ble KCL @ V+ 1. + 12 = 14 = 0 KCL @ V Iz = 14 + + = 0 Vo-V 2K VIN-V+ IK Vo-V. IK V-0 IK Vo-V + 2 VIN - 2 V = 0 Vo-V. = V-0 Vo = 3 V+ - 2 VIN (1) .5 Vo = V. (2) (a) Vo = 3 ( .5 Vo ) - 2 VIN -.5 Vo = - 2 VIN V =V+ (b) Vo = 4 VIN Vo = 4 (2V) (c) Gain = Vo/Vin = 4 Gain 4 Vo = 8V Vo = 4 VIN >
