Question

The amplifier as shown has R₁ = 8.2 k ,
R₂ = 160 k and operates from ±12-V power
supplies. (a) What is the voltage gain A_v = v_o/v_i
of the circuit? (b) Suppose input source v_i is not
ideal but actually has a 1.5 k source resistance.
What is the voltage gain A_v = v_o/v_i?

Expert Solution

Step 1

(a)

The given circuit is an inverting amplifier.

Write the expression for the voltage gain of the circuit.

$\begin{array}{rcl} A_{v} & = & \frac{v_{0}}{v_{i}} \\ = & - \frac{R_{2}}{R_{1}} \\ = & - \frac{160 k Ω}{8.2 k Ω} \\ = & - 19.51 \end{array}$
