Implementation of low frequency band pass filter by 3-OTA based floating active inductor

This paper presents a competitive alternative to conventional passive spiral grounded inductor by realising a 3-OTA CMOS floating active inductor circuit. The realised floating active inductor has been used to implement a low frequency band pass filter design. The designed floating active inductor shows a high frequency operating range with wide tuning capability. The simulation of the proposed grounded active inductor and implementation of band pass filter in low frequency domain are carried out by using Cadence Virtuoso UMC 180 nm technology by Spectre simulator.
