Abstract
A sensor for sensing an analyte includes capacitive elements, each having a pair of electrodes separated by a dielectric wherein the dielectric constant of the dielectric of at least one of the capacitive elements is sensitive to the analyte, the sensor further including a comparator adapted to compare a selected set of capacitive elements against a reference signal and to generate a comparison result signal, and a controller for iteratively selecting the set in response to the comparison result signal, wherein the sensor is arranged to produce a digitized output signal indicative of the sensed level of the analyte of interest. An IC comprising such a sensor, an electronic device comprising such an IC and a method of determining a level of an analyte of interest using such a sensor are also disclosed.
