摘要：

Fault modeling is the key and the difficulty of analog and mixed-signal circuits. The existing fault model include resistance model, perfect switch model, MOS transistor width-length ratio model and slope fault model, these methods have succeed in a certain extent, but also existed much limitation. In this paper, on the basis of research into slope fault model, this paper presents a new fault model is improved slope fault model. The fault model utilizes piecewise linear function to approximate the nonlinear analog circuit, and solve the problem of tolerance by using eulerian length. The experimental result is given to clarify our approach and to show its efficiency. This research provides theoretical foundation for the research of analog and mixed-signal circuits.
