Remote sensing devices continuously send/receive signals and these signals or radio waves are transmitted/received via a transmission line to/from a receiver/transmitter which has a filter that selectively sorts out the signals and only passes a desired range of signals. In this research work, a high pass filter has been designed with CSDG MOSFET. The CSDG MOSFET being a capacitive model allows for better filtering of low frequencies and passes through a frequency range of 200 GHz (0.2 THz) efficiently. By placing capacitors in parallel, the design requires smaller capacitance values to be used. In addition the desired range of frequencies can be achieved from the inversely proportional relationship between frequency and capacitance. The gain and other parameters of the high pass filter have been analyzed with and without a CSDG MOSFET. Finally, it has been demonstrated that the third order high pass filters performs better with the CSDG MOSFET.
