DESIGN AND PERFORMANCE ANALYSIS OF LOW POWER BAND STOP FILTER

In this paper, design and simulation of High performance Band-stop filter based on CNTFET-COTA using 45 nm technology node is proposed. The Cascode Operational transconductance amplifier (COTA) is an amplifier whose differential input voltage produces an output current. It is a voltage controlled current source (VCCS). Further, CNT technology is used to design and simulate proposed structure at 45 nm technology node. The proposed structure uses carbon nanotube field effect transistor. In a CNTFET, the channel is made up of parallel combination of SWCNTs. It is observed that the proposed BSF is also consuming low power of 42 µW.
