Abstract :
This paper describes a new 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 mirocomputer. This sensor, which has been designed for biomedical applications, has a temperature range from 30°C to 46°C, an accuracy of ±0.1°C, a resolution of 0.01°C and a minimum supply voltage of only 2.5V.
