Low frequency noise in SOI transistors (Invited Paper)

With the inherent advantages in SOI CMOS technology, minimizing DC and switching floating body effects have enabled high speed digital processors with more than a 25% improvement over bulk silicon CMOS design. Currently, there is a need for a more comprehensive understanding of AC characteristics on SOI CMOS technology for mixed-mode baseband and RF (radio frequency) applications. The objective of this paper is to present a study of unique AC floating body effects and the resultant low-frequency noise overshoot phenomenon in SOI CMOS technology. Further study of their impact on the RF arena will also be discussed.
