Research Abstract |
A built-in test circuit is proposed to detect an open defect in a CMOS IC by means of appearance time of dynamic supply current of the IC. Also, a test method based on the dynamic supply current with on the test circuit is proposed. A layout of an IC embedding the test circuit has been designed and an IC has been prototyped. It is shown by Spice simulation and some experiments that an open defect in the IC can be detected by the test method.
