Subthreshold slope modulation in G4-FET transistors
We describe the operation of the novel SOI four-gate transistor (G4-FET) in the subthreshold region. The subthreshold slope, which may be defined with respect to either the junction gates or MOS gates, is adjustable using the remaining gates. A comparison of conventional MOSFET swings and G4-FET swings shows improved subthreshold slope. Systematic experimental data and simulations show the bias conditions for optimized performance.
