On-line BIST for testing analog circuits
Jaime Velasco-Medina, I. Rayane, M. Nicolaidis · 2003
In this paper, we present a new online built-in self-test (BIST) approach for testing analog circuits. It uses a current window comparator and current-based checker circuits for processing the test response of the analog parts in mixed-signal integrated circuits. Online analog BIST capability is achieved by using high-speed current-mode circuits. A leapfrog filter has been considered as a test vehicle, and simulation results show the feasibility and effectiveness of the proposed BIST approach.
