| Research Abstract |
The aim of this project is to build up a design system for analog circuits in mixed-signal LSIs, which are expected to play an important role in 21st century. The following results are obtained in the project.
(1) In order to build such a system analog basic building blocks under low-power supply voltages are proposed. The circuits are applied to a synthesis of a △ΣAS Analog-to-Digital converter as an example.
(2) Switched-capacitor circuits are discrete-time signal processing ones and also important analog building blocks Since sitched-capacitor circuits have a clock feedthrough problem, a method to reduce the clock feedthrough effect is proposed.
(3) To help analog circuit designs instead of a small number of analog circuit designers automatic analog circuit design algorithm is proposed.
(4) To reduce noise from digital circuits via a substrate active gurad band circuit is proposed.
Investigation for excellent analog circuit layouts and combination of all results obtained above are left as future problems.
