Abstract :
The RF characteristics of the tri-gate Ω MOSFETs were studied firstly by using 3-dimensional device simulator. Small signal model parameters were extracted using an equivalent circuit and compared with those of a planar MOSFET. The Ω MOSFET shows lower sensitivity of gmb and VT with substrate bias than the planar device. The tri-gale Ω MOSFETs shows a higher cut-off frequency at a lower drain current.
