The paper deals with a new approach to selection of the optimum value of the oscillation frequency towards increasing the efficiency of the oscillation-based test methods in covering hard-detectable short faults in nanoscale technologies. For this purpose, the Describing-Function analysis was used to calculate of the oscillation frequency of a simple oscillator (an analog circuit under test) modeled...
A new on-chip oscillation test strategy for analog and mixed-signal circuits is presented. In the proposed method, on-chip Schmitt trigger is used as the on-chip frequency reference to compensate the influence of process parameter variations. Furthermore, this solution also brings the possibility to implement Oscillation-based Built-In Self-Test (OBIST) for analog and mixed-signal integrated circuits...
