New Z copy- current differencing transconductance amplifier active filter using FinFET transistor based current Mode Universal Filter

Abstract

This research paper presents the design of an active current mode device named Z-copy- Current Differencing Transconductance Amplifier (ZC-CDTA) in conjunction with FinFET (Fin Field-Effect Transistor) transistors. An input bias current can be used to adjust its parasitic resistances at its two current input ports. It is ideal for use in current-mode signal processing, which is steadily more common than voltage-style signal processing, because it operates in current mode on all terminals. The suggested component was implemented using Finfet technology, and its performances were assessed using simulations using cadence tools and linear technology SPICE. They demonstrate the new active element's usage, with a maximum bandwidth of 300MHz. The highest power consumption is 1.01 mW, and the supply voltages can be as low as ±0.1 V. The low-power consumption and wide current range tuning of the suggested Zc-CDTA are achieved.
