Abstract :
A non-invasive methodology of built-in self-test (BIST) has been presented for analog integrated circuits where there are no pins dedicated to introduce test modes or monitor BIST mode results. In this application BIST signature is binary coded to isolate the fault location precisely. This technique is successfully implemented in a 5-stage multi-path feed forward operational amplifier in a standard package when no dedicated pin is available for inducing or monitoring BIST. The implementation uses a calibration phase which makes this technique process variation tolerant
