Abstract
In recent years, trading goods through the Internet becomes very popular and general, make our lives more convenient. Therefore, how to encrypt the transmitted data is a very important issue. In order to create a reliable encryption system, an unpredictable random number generator is necessary. Random number generators usually use naturally generated noise as a signal source to generate unpredictable and aperiodic random numbers. There are some methods using the theory like double oscillator and metastable architecture. However, these methods using the larger circuits may consume more power and chip area. The other way is to generate random number by the large noise signal devices, saves area and power consumption. In this thesis, the relation between the magnitude of the random telegram noise for the drain current and the device operation parameters are found theoretically and verified experimentally. By operating the transistor at a low drain voltage and at the peak of gm, we can get the signal large enough to generate random numbers without using complex circuits, and then a random number generator with a small area and low power consumption can be designed.
