A filter structure designing for an EAS system

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Filter circuit is an important part of the tag identification and detection in the Electronic Article Surveillance (EAS) system and its performance has a direct impact on the tag detection sensitivity. In this paper, we propose a TL084-based filter circuit. By designing the proper parameter values combination of the peripheral capacitance and resistance, we obtain a filter structure with a centre frequency of 11 kHz, and a bandwidth of 20 kHz. Using simulation, we demonstrate that our design has much better filtering characteristics.
