Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output pin and two input pins. The basic role of an opamp is to amplify the voltage difference between the two input voltages. It is also used in filtering or to perform mathematical operations or in signal conditioning.

Question

**Problem Statement:**

1. For the circuit below assume an ideal op amp. Find \( V_o/V_s \).

- \( R_1 = 2k\Omega \)
- \( R_2 = 5k\Omega \)
- \( R_3 = 8k\Omega \)
- \( R_4 = 20k\Omega \)

**Circuit Diagram Description:**

The circuit shown is composed of several components:

- An input voltage source, \( V_s \), connected to a series resistor \( R_1 \).
- A resistor \( R_2 \) connected from the node between \( R_1 \) and \( R_3 \) to ground.
- \( R_3 \) connects to the inverting input (-) of the operational amplifier (op amp).
- The non-inverting input (+) of the op amp is grounded.
- The output of the op amp is connected through \( R_4 \).
- The output voltage is labeled as \( V_o \).

This op amp circuit is configured in a feedback arrangement which suggests it might be an inverting amplifier. The task is to calculate the voltage gain \( V_o/V_s \) based on the given resistances.
