A Built-In Test Circuit for Detecting Open Defects by IDDT Appearance Time in CMOS ICs

Article Preview

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. A layout of an IC embedding the test circuit is designed. It is shown by Spice simulation that an open defect in the IC can be detected with the test circuit.
