Abstract
This paper experimentally analyses the capabilities of an Oscillation-Based Test technique for diagnosis purposes. To evaluate the feasibility of this test strategy, the technique is applied to an Operational Transconductance Amplifier with fault injection capabilities. The application of this methodology has low impact on circuit performances. Voltage and current magnitude have been considered as test observables. The effects of catastrophic and parametric defects (bridges, opens and shorts) are analyzed in this work. Results show that by a right choice of the test observable, this technique provides high fault coverage levels even in the case of process variations.
