The white noise generator circuit is a handy tool that can be used to examine the circuit or a communication line under some random noises to make sure about the stability of the device in real and harsh environments. The current consumption of the device is low, so you can power the circuit using a small 12V-23A battery. if you have access to a 3D printer, you can build a nice enclosure for the circuit. The schematic and PCB have been designed using Altium Designer 22. The output white noise has been tested using the Siglent SDS2102X Plus oscilloscope.
