Paper Abstract

This paper presents architecture of a low power digital clinical ASIC based on NTC thermistor for body temperature measurement. The thermistor coupled externally to a low power astable multivibrator modulate its pulse width. The modulated pulse width is detected in terms of the number of clock pulses counted by a counter. He counter output is processed by on chip processor to display temperature. The ASIC supports many advanced features like self configuration, prediction and self calibration and correction.
