A New Class of Bilateral SISO-(Single Input Single Output) Active Filters Targeted for Health-Care Applications

Abstract

Filter circuits from the very beginning have played a vital role in the broader areas of signal processing and communications systems. In the paper, a new paradigm of bilateral filtering has been presented. The scheme presents a new class of filters that have the ability to work on the either side of the device. The working of the presented circuits in this study commensurates to the working of the transceivers. The initial verification of the circuits was done using nodal analysis and then put for simulation verifications. The Active device used to realise the proposed circuits is the translinear circuit scheme of second generation current conveyor-CCCII. Basic filter signals like low-pass, high-pass, band-pass and band-stop responses were perceived and authenticate the theory proposed. The simulation work was done on Hspice tool using the 45nm PTM CMOS technology node. The detailed analysis of the proposed circuits is open for the readers in this study. The power consumption of the proposed circuits is in the range of $100-200\mu \mathrm{W}$ with $\pm$ 1 V rail to rail voltages. The Proposed circuit is expected to get applicable as the major analog front-end circuit in numerous biomedical devices.
