Abstract: | It is important to understand what the floating-body effects are and how they affect device and circuit behavior. In this regard, this article qualitatively explains the device physics underlying DC and transient floating-body effects, clearly implying their influence on circuits, and thereby giving good insight into PD/SOI CMOS design issues. The article also notes special but practical device and circuit designs for controlling floating-body effects, showing through simulation how PD/SOI offers a significant performance advantage over bulk silicon in low-voltage applications, thereby conveying an assurance that reliable SOI CMOS design is feasible |
