Abstract
A true random number generator including a transistor, a first voltage source, a second voltage source, and a comparator. The transistor has a first electrode, a second electrode, and a third electrode. Two of the electrodes are electrically connected by a channel of conductive nanomaterial. The first voltage source is electrically connected to the first electrode and the second voltage source is electrically connected to the second electrode. The comparator is electrically connected to the third electrode and is configured to classify a measured electrical property at the third electrode as either HIGH or LOW based on a comparison of the measured electrical property with a reference value. The measured electrical property varies over time due to random telegraph signals (RTSs) due to defects in the transistor.
