University of Wollongong School of Electrical, Computer and Telecommunications Engineering ECTE290 2 Analysis: Looking at the figure, we can immediately see that V 2 = V . Using nodal analysis: ( 1 4000 + 1 2000 + 1 6000 ) V 1 − 1 2000 11 = − ( 1 6000 ) V 1 − ( 1 12000 ) V o = Solving for V 1 and V o , V 1 = 6 V and V o = − 12 V Chapter 8, Solution 44. Known quantities: Circuit in Figure P8.44. Find: The output voltage v o . Analysis: The circuit is a cascade of a noninverting opamp with an inverting opamp. Assuming ideal opamps, the inputoutput voltage gain is equal to the product of the single gains, therefore S S F S F v R R R R v ⎟ ⎟ ⎠ ⎞ ⎜ ⎜ ⎝ ⎛ + − = 1 1 2 2 1...
