A novel Dual-Slope Resistance-to-Digital Converter (DSRDC) suitable for single element resistive sensors is presented in this paper. The digital output of the converter is directly proportional to the measurand and is insensitive to the nominal value of resistance, Ro, of the sensor. The choice of fixed resistance employed in a typical DSRDC has been made to be independent of Ro and the constraints on its accuracy have been relaxed. This makes the Resistance-to-Digital Converter versatile, in a manner that it can be easily interfaced with a wide range of resistive sensors having different values of Ro. This task was accomplished by employing an automatic calibration technique, wherein, the reference voltage is digitally adjusted by a Switched Capacitor Controlled Voltage Source (SCCVS). A prototype DSRDC was developed and tested against various values of Ro, which were in-turn emulated using known resistances of values ranging from 25 kü to 200 kü. The worst case error in reading was observed to be less than 0.65 %. © 2016 IEEE.
