Novel Current-Mode Universal Filter using single FTFNTA

Abstract

In this paper, a novel universal filter using single Four Terminal Floating Nullor Transconductance Amplifier (FTFNTA), two capacitors and one/two resistor has been proposed. Sensitivity of pole frequency (ω₀) and quality factor (Q₀) is analysed. Workability of proposed filter has been demonstrated by PSPICE simulations in 0.18µm TSMC CMOS technology.
