Current-mode biquad filter using CNTFET-based ZC-CITA

Singla, Laxya ; Prasad, Dinesh ; Mainuddin, Prof. ; Islam, S. S.


A CNTFET-based z-copy current inverting trans-conductance amplifier (ZC-CITA) has been proposed. The proposed model uses 28 CNTFET-based transistors, 3 current sources and it uses supply voltages of ±2V with 32 nm technology mode. This paper also introduces the validity of ZC-CITA showing its application as biquad filter which has not been designed yet with an added advantage of power reduction. The result has been verified using HSPICE.
