Abstract
A ring oscillator based structure in digital circuits is presented for measuring NBTI and PBTI effects. The proposed test structure enables simultaneous stress of all devices under tests in either NBTI or PBTI mode and measures frequency degradation or the threshold voltage shift. The threshold voltage shift due to NBTI or PBTI can be directly read out in the proposed circuit which has been designed in a 1.2V, 90nm technology.
