A Poly-Resistor Based Temperature Sensing Chip with Digital Output
Year: 2025
Type: article
Abstract: This work presents a resistor-based temperature sensing chip which is designed for applications that require temperature sensing. The core of the design is a poly-resistor bridge, which generates two distinct outputs: one varies with temperature and the other provides a constant reference [2]. These outputs are then processed by a differential amplifier, ensuring reliable signal amplification and enhanced separation of the temperature-dependent signal from the reference. The amplified signal is then digitized using a compact 3-bit ADC, that is realized using an 8:3 encoder. The simplified integration of the resistor bridge, differential amplifier, and ADC demonstrates a practical approach for temperature sensing, offering a versatile solution for systems where basic thermal monitoring is essential [3].
