Abstract
This research presents a gas sensor system featuring a selenized two-dimensional (2D) film as its primary sensing material, integrated with metal-gate-coupled floating gate devices to enable self-convergent calibration. The inherent variability in resistance levels of 2D gas-sensing materials across different devices has been a significant challenge, resulting in substantial deviations of the output signal within the sensing circuit. To address this issue, we introduce a novel self-convergent operational technique, which effectively mitigates the impact of resistance variations thereby enhancing the precision and reliability of gas-sensing outcomes. The proposed gas sensor system promises to deliver consistent and accurate results, even with device-to-device resistance variations, making it a valuable contribution to gas-sensing technology. This work holds substantial potential for various applications requiring highly precise gas detection and quantification.
