Abstract

Interest in air quality is increasing due to the awareness of the seriousness of air pollution, resulting in continuous monitoring of harmful ingredients in the air. Sensors incorporating Internet of Things (IoT) capabilities are required to efficiently collect general user and atmospheric environment information in a wide range. Therefore, it is necessary to develop low-cost, ultra-small, and low-power sensors to install a large number of sensors in a wide range. In this paper, Read-Out Integrated Circuit (ROIC) is proposed to aim to develop low-cost, ultra-small, low-power, and high-sensitivity sensors based on High-Electron Mobility Transistors (HEMT) incorporating IoT functions with semiconductor-type gas sensors. The proposed ROIC utilizes Transimpedance Amplifier (TIA), Delta-Sigma Analog-to-Digital Converter (ADC), and Negative Charge Pump (NCP) in the TSMC 0.18um process.
