Abstract :
A bipolar implantable integrated micropower low-voltage temperature-controlled oscillator has been designed and fabricated, especially for biomedical applications. The circuit is intended to measure body temperatures within the range of 32-42/spl deg/C with an accuracy of /spl plusmn/0.1/spl deg/C. The temperature coefficient has been calibrated to 100 Hz//spl deg/C, although other values are also possible. Power consumption is less than 40 /spl mu/W at a nominal supply voltage of only 2.7 V. The implementation is in standard bipolar IC technology and thick-film technology.
