A direct resistance-to-digital converter (RDC) that is suitable for differential resistive sensors is proposed and analyzed in this paper. The RDC presented here provides a digital output that is linearly proportional to the parameter being sensed by a differential resistive sensor possessing either linear or inverse characteristics. The RDC employs the sigma–delta analog-todigital conversion (...

A multi-sensor system is a chemical sensor system which quantitatively and qualitatively records gases with a combination of cross-sensitive gas sensor arrays and pattern recognition software. This paper addresses the issue of data analysis for identification of gases in a gas sensor array. We introduce a software tool for gas sensor array configuration and simulation. It concerns thereby about...

great effect of three way catalytic convertor (twc) performance on oxygen sensor output voltage has made the sensor (located after catalyst) as the main signal in almost all today’s twc monitoring algorithms. in this paper output voltage of nonlinear oxygen sensor is estimated using a nonlinear autoregressive with exogenous inputs (narx) model. the estimation uses ecu calculated exhaust gas flo...

Unipolar resistive switching memory cells were fabricated using a Mg0.84Zn0.16O2−δ thin film, sandwiched between p+-Si (100) substrate and Cr/Au top electrodes. Electrical measurements showed a large memory window and memory window margin of 107 and 104, respectively. Furthermore, a wide switching voltage distribution gap of 3.6 V between the switching-ON and -OFF processes was obtained for dif...
