Abstract This project is about the design of a smart integrated temperature sensor. It is designed to be implemented in a hearing aid. This means that small area and power consumptions are essentially. A very small circuit has been proposed and simulated and has been possible to use the same circuit to generate both a current with a negative and with a positive temperature coecient which has to be compared. This means that area and power consumptions are kept low and matching problems are avoided. In order to make a digital output a ring oscillator has been used, and again only one oscillator is used. A precision of about -2.1°C/+1.9°C has been obtained. More proposal have been made in order to increase this precision. A layout has not been made and therefore only a working simulation model is presented.
