Abstract

This paper presents the first-ever research on high-voltage stress of analog circuits to enhance their oxide reliability and to reduce the manufacturing cost. The emphasis of this paper is placed on how to properly stress analog circuits and the development of efficient algorithms for generating stress vectors that meet the stress coverage requirement within a feasible stress time.
