A low-power true random number generator using random telegraph noise of single oxide-traps
Ralf Brederlow, R. Prakash, Christian Paulus, Roland Thewes · 2006
A true random number generator is realized by utilizing the noise produced by single oxide traps in small-area MOSFETs in combination with built-in redundancy. The circuit has an area of 0.009mm2in 0.12μm CMOS and consumes 50μW at 200kb/s random output data. The concept is robust against environmental noise and supply-voltage variations and is thus suitable for operation within security controllers
