This thermal noise-based random bit generator leverages the inherent unpredictability of thermal noise to create truly random sequences of bits, vital for security protocols and cryptographic applications. Operating within a frequency range of 0.2 to 2 MHz, the generator is engineered for efficient power use with a quiescent current draw of around 50 uA. The compact design and reliable output make it suitable for applications where secure random bit generation is a necessity, such as in secure communications and data encryption systems.
