Fully-depleted (FD) SOI MOSFET's offer near-ideal properties for analo
g applications. In particular their high transconductance to drain cur
rent ratio allows one to obtain a higher gain than from bulk de,ices,
and the reduced body effect permits one to fabricate more efficient pa
ss gates. The excellent behavior of SOI MOSFET's at high temperature o
r at gigahertz frequencies is outlined as well.
