1
Operation Amplifier

2
Golden Rules of OP Amp 1.i in =0, no current flow into op amp. 2.V + =V - Typically one end of op amp is connected to ground, therefore, V + =V - = 0V, virtual ground. Often V + is connected to ground to avoid stability problem.

3
Inverting Amplifier Feedback resistor, always to negative input

4
Summing Amplifier: Add Circuit If R S1 =R S2 =…=R SN =R S

5
Non-innverting Amplifier Feedback resistor, always to negative input

6
Voltage Follower Applications: Since the input resistance of an op amp ∞, it will have no effect on the input.

7
Differential Amplifier Very useful if both signals are corrupted with noise: Electrocardiogram (EKG)
