A 0.12mm² Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C

Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm ² ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm ² resistor-based sensor that uses a...
