Q2. Find resistance value to get desired gain 
 For the ideal op-amp given below, what is the value of resistance Rx to get gain    V_{out}/V_{in} = -A_f  ? (Assume   A_fR_1>R_2+R_3 ).

Answer

\frac{R_2R_3}{R_2 + R_3}

Answer

\frac{R_2R_3}{R_1 + A_f(R_2 + R_3)}

Answer

-\frac{R_2R_3}{R_1 + R_2 + R_3}

Answer

-\frac{R_1R_2}{A_fR_1 + R_2 + R_3}

Answer

-\frac{R_2R_3}{-A_fR_1 + R_2 + R_3}
