Objective: The radio-frequency switches can be designed using MOSFET,
FinFET, and various structured MOSFET for example Double-gate, Omega, and gate all
around etc. In this research work author has analyzed the effect of porous spaces on the
RF switching process.
Method: In the design process of radio-frequency switches some porous spaces generated
at the time of fabrication. These porous spaces reduce the performance of the switch
and also slower the switching speed. To find out the possibilities of occurrence of these
spaces and the performance parameters, a device has been analyzed in this manuscript.
The analyzed RF switch has been designed by the Cylindrical Surrounding Double-Gate
Conclusion: In the present research work, the analysis is centered around the effect of
these porous space or voids available in between the external channel and internal channel
region of the MOSFET. This analysis is in terms of device resistance, capacitance,
drain current and various noises for the application of a device as a radio-frequency
switch in the wireless communication systems.
