ABSTRACT:
A low power analog linear temperature sensor integrateable with digital and/or analog circuits in CMOS fabrication processes. The sensor is accurately calibrateable at a single temperature that yields a linear relationship between measured differential voltage and temperature over a wide variety of temperature ranges. The sensor provides stable voltage and current references that are essential for wireless sensor platforms. There are many applications where sensors require stable voltage/current references and the physics of the sensor's transduction mechanisms are themselves temperature dependent. Wireless platforms such as, but not limited to, passive RFID tags with the addition of on- or off-chip sensors provide a low cost solution for a variety of low cost sensor applications.
