Design of Voltage Mode 6th Order Elliptic Band-pass Filter Using Z-Copy Current Follower Transconductance Amplifier ( ZC-CFTA)

This paper describes the realization of the new configuration of an active element namely, z copy current follower transconductance amplifier (zc-cfta). in this study, the elliptic 6th order voltage-mode (vm) band-pass filter was configured based on the zc-cfta, which operates at a high frequency of about 30 mhz. the active element also contains floated and grounded inductance with one capacitor. the zccfta which is an abb (active building block) is configured with a passive element that is the 6th order elliptic band pass filter. the results lt-spice software simulation using 0.18μm cmos processing parameter show that the designed filter could be operated at a supply voltage of 0.9v and it offers the advantages of a small size and high gain.
