Gentag Successfully Tests Temperature Sensor Circuit
Gentag has successfully tested an ultra linear, low power single calibration temperature sensor circuit which can be directly integrated on any chip for either the Gen 2 UHF or the 13.56 MHz global RFID markets.

It could be used as a reference circuit in order to make accurate, low cost passive RFID sensors, BAP sensors or active sensor tags. The sensor could be integrated with the RFID chip itself and occupies little space. They only require a single temperature calibration point which enables generous fabrication cost savings for the manufacturer and the end user.

Its temperature sensor is analog in nature and is designed to consume lil power when it is on and reading out tag temperature and no power when they are off. They can be switched on and off quickly and can be fabricated by making use of generic digital CMOS technology. A reference for other possible analog RFID sensors could be established by the unique circuit. As most of the sensors are temperature dependant therefore it becomes necessary that an independent measure of temperature be made for accurate RFID sensor calibration and robust measurements of variables such as humiditylinks, pressure and conductivity.

This technology has emerged as a unique, low cost solution for wireless temperature monitoring and has opened the way for wide deployment and implementation of low cost passive RFID sensor tags and a variety of consumer and industrial applications.
