This work reports on analytical modeling and investigation of Resonant Suspended-Gate MOSFETs (RSG-MOSFET) as future solutions for RF applications including MEMS and ICs. Pure metal-metal capacitive detection for resonators is shown to be the most limiting factor for the use of high frequency resonators in circuit application. We demonstrate the necessity of using a MOSFET detection instead of a capacitive one for very high frequency resonators. The analytical model is based on the Resonant Gate Transistor (RGT) model that was adjusted to include new resonator geometries, scaled nm-to-ìm device dimensions and based on a more advanced transistor model.
