In this paper, we have analyzed the image acquisition of the Cylindrical Surrounding Double-Gate (CSDG) MOSFETs for the purpose of RF switch for the advanced wireless telecommunication systems. The proposed model will emphasize on the basics structure of the single image sensor for two dimensional images of a three dimension devices, so that we can obtained a satisfied or say smooth device structure and hence some of its parameter. The physical significance of these basic structure elements are also has been discussed.
