A sensor signal conditioning circuit using a generalized impedance converter (GIC) is presented. The circuit is dc polarized and able to feed a constant current to one or more sensors. GIC input impedance is kept high to maintain the load current of its input reference voltage very low. Experimental results show the feasibility of the dc modified GIC as an electronic conditioning circuit for two resistive temperature detectors (RTD-Pt100) sharing the same current loop.
