| Research Abstract |
In this study, we developed analog and digital circuit design techniques that are tolerant to process and temperature variations. By developing ultra-low power current reference circuit, we can monitor the condition of threshold voltage of MOSFET in each LSI chip. We also proposed compensation architecture of digital circuits by using on-chip variation monitoring circuit. Moreover, we developed robust operational amplifier and comparator circuit that are fundamental analog circuit building blocks. For analog and digital signal processing systems, clock reference circuit and analog-digital converter were investigated. We demonstrated that these circuits operate robustly against process and temperature variations.
