Abstract: In this work, cascode operational transconductance amplifier based High Pass filter is proposed using advance technology. Cascode Operational Transconductance Amplifier (COTA) is a new class of operational amplifier (OP-AMP). Flexibility and the tunability are the big advantages of COTAs. It has been designed and simulated using novel Carbon Nano Tube (CNT) based MOS structures and conventional MOSFETs at 45nm technology node. The proposed structure is useful for analog applications in nano electronic circuits. It is observed that the proposed HPF is also consuming low power of 129 nW. The proposed HPF is simulated using 0.9 V.
