Abstract :
In this work, we explore the ability of OBT for testing OTA-C filters with a more complex OTA configuration than in previously reported one. Adopting a second-order structure as a case study, we use a non-linear block in the feedback loop in order to force the oscillations. The evaluation of the test quality is made by fault simulation. The simulation results show that the filter present very good fault coverage values.
