Resistor-based Temperature Sensors in CMOS Technology

This thesis describes the design and implementation of integrated temperature sensors based on the temperature dependency of CMOS resistors.

A 10 fJ·K ²Wheatstone Bridge Temperature Sensor with a Tail-Resistor-Linearized OTA

This article describes a highly energy-efficient Wheatstone bridge temperature sensor. To maximize sensitivity, the bridge is made from resistors with positive (silicided diffusion) and negative (poly) temperature coefficients. The bridge is balanced by a resistive (poly) FIR-DAC, which is part of a 2nd-order continuous-time delta-sigma...
