CURRENT INTEGRATOR WITH WIDE DYNAMIC RANGE

摘要

The invention relates to a determination circuit for measuring a current. The invention also relates to a method for measuring a current using such a determination circuit and to a computer program product adapted, when being executed by a processor, to integrate a current using such a determination circuit. According to the invention an integration circuit comprising the determination circuit is reset each time the integration value of the current exceeds the threshold until expiration of a predefined maximum integration time. The invention increases the accuracy of integrating a current and also increases the dynamic range of currents that can be integrated. To further increase the dynamic range of currents as can be integrated the determination circuit may comprise circuits having different gain factors.
