A Method of Transistor Degradation Estimation Using Ring Oscillators
Tatsunori Ikeda, Yukiya Miura (Tokyo Metropolitan Univ.) DC2013-15
Abstract (in Japanese) (See Japanese page) 
(in English) Aging called Negative Bias Temperature Instability (NBTI), Negative Bias Temperature Instability (NBTI) and Chanel Hot Carrier (CHC) occurs in nanoscale transistors, which is a major factor for degrading the performance of LSIs. Operating speed of transistors is decreased by aging, and LSI malfunctions by a delay in signal propagation. In this paper, we present a method for estimating the amount of increase in delay time and a threshold value per one transistor from change in the period of two ring oscillators by aging. It was verified by circuit simulation that the proposed method can estimate with an error rate of less than 5% of the delay time increase and an error of less than 2% of the threshold voltage increase.
