| Research Abstract |
This research introduces a built-in self test(BIST) system , which is a method of Design for Testability for analog LSI test. We explored the analog signal processing and introduced a systematic test method for analog ICs. The developed BIST generates a set of preset analog signals, and input them into each analog device in chip in turn. When a device is activated for inputs, its output signal is also sampled. The sampled signal is then quantized by an ADC, and its amplitude/frequency/phase/delay characteristics are calculated by a digital signal processing unit. These characteristics then are compared with the expected outputs by the control logic unit. The control logic unit finally judges if a circuit failure is determined. The measurement results from the test chip confirmed the testability of the introduced BIST system.
