DIGITAL TEMPERATURE SENSOR CAPABLE OF REDUCING SIZE

摘要

A digital temperature sensor that can be miniaturized is published. Since the digital temperature sensor of the present invention determines the data value of digital temperature data by the DSM method, the sensing precision is very high. In addition, in the digital temperature sensor of the present invention, the voltage level of the comparison current and ultimately the comparison sensing signal is directly controlled by the code value of the switching control code. As a result, the digital temperature sensor of the present invention is implemented in a DSM method and is easy to miniaturize.
