Temperature Sensor

The need for a low-power CMOS temperature sensor is increasing drastically. For any system, temperature monitoring is a must to ensure the operation safety. With the emergence of IoT, temperature sensors will be embedded all around us. This research continuously pushes the limit of accuracy, resolution, temperature range, and power consumption by inventing different sensing mechanisms and innovative circuit techniques. Recently, we have developed linear relationships between the current ratio and temperature by utilizing the intrinsic device mismatch. We are actively exploring utilizing device variability as a metric for temperature sensing. Our latest results show great promise as we can eliminate many sources of errors.
