Abstract

Transformation of different types of switched-capacitor (SC) biquad filter stages based on Fleischer-Laker biquad SC structure in order to support oscillation based testing (OBT) have been proposed. The derived solutions are based on the generic Fleischer-Laker biquad SC structure assuming ideal characteristics of the employed components. In this paper, we explore the operation of the proposed OBT structures in the case of non ideal components. Furthermore, the efficiency of the proposed OBT schemes in terms of achieved fault coverage in comparison with other test methods is discussed.
