 Abstract
A resistance deviation-to-time interval converter based on dual-slope integration using second generation current conveyors (CCIIs) is designed for connecting resistive bridge sensors with a digital system. It consists of a differential integrator using CCIIs, a voltage comparator, and a digital control logic for controlling four analog switches. Experimental results exhibit that a conversion sensitivity amounts to over the resistance deviation range of and its linearity error is less than . Its temperature stability is less than in the temperature range of . Power dissipation of the converter is 60.2 mW.
