inverting and non inverting are swapped- fix later

Ideal Op Amp Circuits

Inverting

Closed-Loop Gain: $G = \frac{V_O}{V_I} = 1 + \frac{R_2}{R_1}$

• Finite Open-Loop Gain: $1 + \frac{R_2}{R_1} << A$

• Weighted Summer

  

Non-Inverting

Closed-Loop Gain: $\frac{V_o}{V_i} = - \frac{R_2}{R_1}$, for $A = \infty$

• Very high input resistance

Difference Amplifiers

Designed with $\frac{R_4}{R_3} = \frac{R_2}{R_1}$, where $V_O = (\frac{R_2}{R_1})(V_{I_2}-V_{I_1})$

• Instrumentation amplifier
