title = "Fast characterization of PBTI and NBTI induced frequency shifts under a realistic recovery bias using a ring oscillator based circuit",
abstract = "A ring oscillator based circuit for separately characterizing PBTI and NBTI induced frequency shifts is demonstrated in a high-k metal gate process. The proposed design, for the first time, supports AC stress with a realistic recovery condition. Other benefits over the previous works include sub-400 nanosecond measurement time, sub-picosecond resolution and a simple calibration procedure. Detailed stress and recovery measurements under different voltage and temperature test conditions are presented and analyzed.",
