A Resistor-Based Temperature Sensor With a 0.13 pJ·K² Resolution FoM

This paper describes a high-resolution energy-efficient CMOS temperature sensor, intended for the temperature compensation of MEMS/quartz frequency references. The sensor is based on silicided poly-silicon thermistors, which are embedded in a Wien-bridge RC filter. When driven at a fixed frequency, the filter exhibits a temperature-dependent...

A High-Resolution, Resistor-Based Temperature Sensor

This thesis focuses on developing a high-resolution, energy-efficient smart temperature sensor. A resistor-based temperature-sensing structure is chosen as the core of the sensor. To digitize the core output, a low-noise readout circuit is developed. The design was fabricated in a standard CMOS technology, and the measurements were conducted to...
