Abstract: In this paper, design and simulation of High performance Band-pass filter based on  CNTFET-COTA using 32nm 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). There is usually an additional input for a current to control the amplifier's transconductance. The COTA is similar to a standard operational amplifier in that it has a differential input stage and that it may be used with negative feedback. The COTA is used as the active building block. It is a new class of Operational Amplifier (OP-AMP). It has flexibility and tunability unlike Op Amp. Further, CNT technology is used to design and simulate proposed  structure at 32 nm technology node. The proposed structure uses Carbon Nanotube Field Effect Transistor (CNTFET). In a CNTFET, the channel is made up of parallel combination of SWCNTs. It is observed that the proposed BPF is also consuming low power of 553 nW.
