Abstract

The authors describe a novel smart temperature sensor with on-chip signal processing. The output signal consists of a temperature-dependent frequency and a reference frequency that are time-multiplexed and can be read out by a microcomputer. This sensor, which has been designed for biomedical applications, has an accuracy of ±0.1°C in the temperature range of 32-44°C and a minimum supply voltage of only 2.5 V
