Cards have: Voltage Divider + Vs - A Vout= Vs / A R 1

Cards have: Voltage Divider + Vs - A Vout= Vs / A R 1 + Vs - R 2 V 2= Vs. R 2 R 1+R 2 Voltage Divider System Side Circuit Side 3

Start with System Side Rth + - Vth Thevenin Equivalent Start with a Voltage

Start with System Side Rth + - Vth Thevenin Equivalent Start with a Voltage Divider + Vs - A Vout= Vs / A Divide It 4

Build a Circuit: Vo = 3 V 1 + 4 V 2 V 1

Build a Circuit: Vo = 3 V 1 + 4 V 2 V 1 V 2 X Vo=AV 1+BV 2 A + X B Non-Inverting Summer 6

Build a Circuit: Vo = 3 V 1 + 1/4 V 2 V 1

Build a Circuit: Vo = 3 V 1 + 1/4 V 2 V 1 V 2 X Vo=AV 1+BV 2 A + X B Non-Inverting Summer • Problem: • G 1 & G 2 >=1 Non-Inverting Summer 7

Build a Circuit: Vo = 3 V 1 + 1/4 V 2 Vin Vout

Build a Circuit: Vo = 3 V 1 + 1/4 V 2 Vin Vout =AVin X V 1 AA=3 V 2 Vin X A-A=-1/4 Inverting Amplifier A + X B Non-Inverting Summer Non-Inverting Amplifier Vout = -AVin X Vo=AV 1+BV 2 Vin Vout = -AVin X A-A=-1 Inverting Amplifier 8

Build a Circuit: Vo = 3 V 1 + 1/4 V 2 Vo= Vs

Build a Circuit: Vo = 3 V 1 + 1/4 V 2 Vo= Vs (R 1+R 2)/R 2 A=3 Non-Inverting Amplifier Non-Inverting Summer Vo = Vs (-Rf/Rs) Inverting Amplifier AA=-1/4 Vo = Vs (-Rf/Rs) Inverting Amplifier AA=-1 9

Simple Circuit Cards Work When Vo = Vs (-Rf/Rs) Inverting Amplifier Zout << Vin

Simple Circuit Cards Work When Vo = Vs (-Rf/Rs) Inverting Amplifier Zout << Vin Vo = Vs (-Rf/Rs) Inverting Amplifier Zin Vout =Vin X AA=1 Unity Gain /Buffer Amplifier OR Buffer Between Vo = Vs (-Rf/Rs) Inverting Amplifier 10
