Hardware Simulation for Bio-Signal Acquisition System

Author : Ravi M 1 Suma K V 2

Date of Publication :7th June 2016

Abstract: Designing an amplifier board for Bio-signal amplification and filtering requires both software based simulation and hardware implementation of design and testing. There are many tools available today like LabViewTM, multisimTM etc for software simulation with available components. But hardware testing becomes difficult as the bio-signals are very low amplitude and low frequency signals and can be easily affected by coupling noise running through wires on breadboard and in the surrounding. The final testing requires PCB fabrication with proper noise reduction. It is a much time consuming and costly process as it requires multiple PCB to be fabricated for testing of each design. To solve this issue a single simulation board is designed in which all the stages in Bio-Signal amplifier stages are designed with proper noise reduction techniques. MultisimTM is used for simulation of each stage and final PCB is designed with proper noise reduction.
