Abstract: In this paper, Carbon Nanotube (CNT) based Universal filter for Biomedical Applications  are proposed at 90 nm technology node. Cascode Operational Transconductance Amplifier (COTA), a new class of operational amplifier is used as basic building block. The proposed Universal filter is electronically tunable, flexible and low power consuming.  Average Power dissipation in the proposed structures i.e. Low-Pass (LPF), the High-Pass (HPF), the Band-Pass (BPF) and Band Reject (BRF) are very small. It has been designed using 20 CNTs, 1.5 nm Diameter of CNTs, 20 nm Pitch of CNTs.  The low power dissipation, use of high speed CNT based devices and small devices dimensions at 0.9V supply voltage make proposed structures suitable for biomedical applications.

Keywords: CMOS, CNTFET, Cascode -OTA, Power consumption, Universal Filter
