Abstract

This paper presents an energy-efficient resistor-to-digital converter (RDC) designed for detecting a wide range of relative humidity. The proposed RDC leverages a deltasigma architecture, enabling a high linear readout range while maintaining excellent power efficiency. The design achieves a resolution of 0.2 Ω with a rapid measurement time of 0.3 ms, while consuming only 87 μW. The energy efficiency Figure of Merit (FoM) is 10.12 pJ per measurement.
