Statistical Analysis of Random Telegraph Noises of MOSFET Subthreshold Currents Using a 1M Array Test Chip in a 40 nm Process

IEEE Journal of the Electron Devices Society, 2021
It is difficult to measure the random telegraph noises (RTN) of MOSFET subthreshold currents at the sub-pA level directly and accurately. In this work, we used a charge integration method similar to the operation of the CMOS image sensors (CIS) to ...
