Question
**Problem 4.13**

*Objective:* Obtain an expression for the voltage gain \( G = \frac{v_o}{v_s} \) for the circuit in Fig. P4.13.

---

**Figure P4.13:** Circuit for Problem 4.13.

**Description of the Diagram:**

The circuit in Figure P4.13 is an operational amplifier (op-amp) configuration. It includes:

- **Resistor \( R_1 \)** connected at the inverting input of the op-amp.
- **Resistor \( R_2 \)** connected from the output of the op-amp to the inverting input, forming a feedback loop.
- **Resistor \( R_3 \)** connected from the output to \( v_o \).
- **Resistor \( R_L \)** connected to the ground from \( v_o \).
- **Source voltage \( v_s \)** connected through resistor \( R_s \) to the non-inverting input (marked with a plus sign) of the op-amp.

The objective of this problem is to derive the voltage gain \( G \) of this circuit configuration.
