A 0.25 mm²-Resistor-Based Temperature Sensor With an Inaccuracy of 0.12 °C (3σ) From -55 °C to 125 °C

This paper describes a compact, energy efficient, resistor-based temperature sensor that can operate over a wide temperature range (-55 °C-125 °C). The sensor is based on a Wheatstone bridge (WhB) made from silicided poly-silicon and non-silicided poly-silicon resistors. To achieve both area and energy efficiencies, the current output of the WhB...
