The influence of the transient floating body on CMOS/SOI circuits is also studied and analyzed,taking a ring oscillator as an example.

The well\|behaved characteristics of device and circuit are achieved,the propagation delay per\|stage of 101\|stage 0 8 micron CMOS/SOI ring oscillator is 45ps with 5V supply voltage.
