Abstract
This paper presents a current measurement system operating in an automotive environment. The architecture incorporates a SigmaDelta modulator with a common-mode control circuit. A new technique of error compensation of circuit imperfections is presented. An experimental prototype has been produced that achieves a resolution of over 12 bits. Results show that the proposed technique improves the common-mode rejection ratio of the system.
