Abstract
This paper presents novel Built In Sensor (BIS) to test a well-known analog building block; the Current Feedback Operational Amplifier (CFOA). The proposed BIS tests on the terminal characteristics of the analog block. It has no voltage degradation. Moreover, it has a simple design, very small area and can detect both short and open circuit faults. Simulations are made to test CFOA-based universal analog filter. A comparison with the conventional IDDQ test is given and it proves that the proposed BIS has a superior performance. © 2009 IEEE.
