DC testing of analog integrated circuits with piecewise linear approximation and interval analysis
Domine M. W. Leenaerts, J. van Spaandonk · 1993 IEEE International Symposium on Circuits and Systems · 2002
A test method for analog circuits is presented which is based upon simple DC measurements that can be performed directly on the wafer. The authors' method handles parameters at various levels, e.g., process, device and circuit parameters. In contrast to other methods that use parameter intervals, their method obtains a mathematical relation between the parameters, which results in a more powerful decision criterion. The method may be used as the basis for automatic testing.>
