A low-cost temperature sensor with on-chip sigma-delta ADC and digital bus interface was realized in a 0.5 /spl mu/m CMOS process. Substrate PNP transistors are used for temperature sensing and for ...

The temperature sensor degraded in phosphate-buffered solution over 48 days, leaving the encapsulation layer. This study provides insight into enhancing the sensitivity of temperature sensors with ...

A 3-D-hybrid plasmonic waveguide (HPWG) cascaded ring resonator-based temperature sensor is studied in the infrared (IR) spectral regime. The proposed design achieves high sensitivity and precision in ...
