| Research Abstract |
In this study, we have studied on improving test efficiency of system LSIs. To achieve such efficient manufacturing test, we introduced structural test methods which are usually used in testing of digital circuits into testing of analog circuits.
We have evaluated transfer characteristics between input stimulus and output signals by using SPICE simulator. In addition, we also proposed and evaluated on-chip signal sampler circuits which are necessary for on-chip testing of analog circuits. We designed and evaluated analog-to-digital conversion circuits and time-to-digital conversion circuits. The experimental results showed that those circuits can be applied for efficient testing of analog circuits with high precision.
