Effect of CSDG MOSFET based high pass filter on signaling

Abstract

This research work looks at the design of active high pass filter that can be used in mobile communication systems. These systems make use of trans-receiver system. This type of system is commonly used in handsets. In this research work the proposed filter has been designed with a Cylindrical Surrounding Double-Gate (CSDG) MOSFET and operates at cutoff frequency of 100 GHz (0.1 THz). A CSDG MOSFET is an extension of DG MOSFET technology. It is structured by rotation of DG MOSFET with respect to its reference point to form a hollow cylinder. It consists of two gates, one drain and one source. The gain, phase, and return loss of the high pass filter has been analyzed with and without CSDG MOSFET using electronic device simulator. Finally, it has been demonstrated that the third order high pass filters performs better with the CSDG MOSFET.
