摘要
A new digital BIST structure is proposed in this paper. During test mode, the Op Antp under test is placed in a voltage follower configuration in order to detect its slew-rate deviation, or in a comparator configuration in order to detect its signal propagation delay deviation. The test stimuli and the BIST control signals are simply derived from the test control signal TST using delay elements and logical gates. The test response is analyzed by using a pure digital circuitry. Simulation results show the effectiveness of the proposed technique with a low area overhead.
