Abstract
A transducer circuit, particularly for monitoring current, compensates for offset in the transducer output by sampling the output periodically at a moment at which the output is known, and storing the sampled value as an offset. The offset is compared with subsequent outputs from the transducer to provide a difference signal which is the compensated output of the transducer. When the calibrated output of the transducer is non-zero at the said moment, the non-zero value is added as a reference to the compensated value to correct the magnitude of the transducer output.
