Abstract
Transformation rules for oscillation based test for different types of switched-capacitor (SC) biquad filter stages based on Fleischer-Laker biquad SC structure are proposed. In our earlier work, a solution for all-pass SC biquads has been reported. In this paper we generalize the approach to other classes of SC filter biquads. Theoretical background of the proposed approach is described and a set of practical design-for-test rules for each of the addressed SC structure is provided. Proposed oscillation based test structures can be included into a built-in self-test design with minimum hardware overhead. DOI: http://dx.doi.org/10.5755/j01.itc.42.1.1695
