Q1. Find the closed loop gain and output impedance 
 A  non-inverting amplifier employs an op-amp with a finite loop gain   A_0  , and output impedance   R_{	ext{out}} , as shown below. Find the closed loop gain   v_{out}/v_{in}  and output impedance.

Answer

\frac{v_{out}}{v_{in}} = \frac{A_0(R_1+R_2)}{R_1 + R_2 +A_0R_2 + R_{out}}  and Output Impedance   = \frac{(R_1+R_2)R_{out}}{R_1+R_2+A_0R_2+R_{out}} .

Answer

\frac{v_{out}}{v_{in}} = \frac{A_0(R_1+R_2)}{R_1 + 2R_2 + A_0R_{out}}  and Output Impedance   = \frac{(R_1+R_2)R_{out}}{R_1+2R_2+A_0R_{out}} .

Answer

\frac{v_{out}}{v_{in}} = \frac{A_0(R_1+R_2)}{R_1 + R_2 +A_0R_1 + R_{out}}  and Output Impedance   = \frac{(R_1+R_2)R_{out}}{R_1+R_2+A_0R_1+R_{out}} .

Answer

\frac{v_{out}}{v_{in}} = \frac{A_0(R_1 - R_2)}{R_1 + 2R_2 + A_0R_{out}}  and Output Impedance   = \frac{(R_1 - R_2)R_{out}}{R_1+2R_2+A_0R_{out}} .

Answer

\frac{v_{out}}{v_{in}} = \frac{A_0(R_1-R_2)}{R_1 + R_2 +A_0R_2 + R_{out}}  and Output Impedance   = \frac{(R_1-R_2)R_{out}}{R_1+R_2+A_0R_2+R_{out}} .
