Abstract
A versatile resistive temperature sensor for Internet-of-Things (IoT) is presented, based on an all-dynamic architecture. This allows efficient scaling of power with conversion rate, enables optional oversampling for an adaptable resolution, and provides efficient adaptability to different resistor values. A new double-sided measurement mode is proposed to compensate for offset, 1/f noise and non-idealities at system level. The sensor achieves a minimum power consumption of 174pW at 1S/s measurement rate, which scales up to 488.3nW at 100kS/s. It offers a nominal rms resolution of 0.61∘C and a resolution FoM as low as 1.82pJ∙∘C2.Keywords
