A 6.6-μW Wheatstone-Bridge Temperature Sensor for Biomedical Applications

This letter presents a compact, energy-efficient, and low-power Wheatstone-bridge temperature sensor for biomedical applications. To maximize sensitivity and reduce power dissipation, the sensor employs a high-resistance (600 kΩ ) bridge that consists of resistors with positive (silicided-poly) and negative ( n -poly) temperature coefficients...
