Oscillation-Based Test in Mixed-Signal Circuits [Paperback]

This book presents the development and experimental validation of the structural test strategy called Oscillation-Based Test  OBT in short. The results presented here assert, not only from a theoretical point of view, but also based on a wide experimental support, that OBT is an efficient defect-oriented test solution, complementing the existing functional test techniques for mixed-signal circuits.
