Unformatted text preview: To synthesize v O = A v I + B Determine A and B from your requirements 1. Connect to v 1 : V + if B is negative V − if B is positive 2. Choose R 2 and R 1 so that v O = B when v I = 0 3. If A is negative: Connect v I to the v 2 input and ground the v 3 input Choose R 3 for the correct gain value, A = − R 2 / R 3 4. If A is positive: Connect v I to the v 3 input Calculate the gain as A = (1 + R 2 / R 1 ) a) If the calculated gain is too small then ground the v 2 terminal and choose R 3 to get the desired gain value, A = [1 + R 2 /( R 1  R 3 )] b) If the calculated gain A = (1 + R 2 / R 1 ) is too large, remove R 3 and use a voltage divider between the input signal and the v 3 input terminal. 5.
