Random Noise Generator

Overview

This project presents the design and implementation of a Random Noise Generator. The circuit was first simulated using LTspice to analyze noise behavior, and then implemented as a 2-layer PCB using KiCad.

The project demonstrates the complete workflow from simulation to hardware design.
