VCO (Voltage-Controlled Oscillator) with Op-Amps

Overview

This experiment demonstrates a voltage-controlled oscillator (VCO) circuit using operational amplifiers, which produces a frequency that varies with the input voltage.

Components Required

• Op-Amp
• Capacitors
• Resistors
• Variable resistor (for controlling frequency)
• Power supply
• Breadboard and wires

Procedure

1. Configure the op-amp with timing components to create the oscillator circuit.

2. Adjust the input voltage and observe the change in output frequency.

Expected Result

The output frequency will vary based on the input voltage, demonstrating the VCO principle.
