Current measurement circuit

摘要

A circuit for the measurement of current in a load includes a non-linear element for transforming a current into a voltage and includes a fuzzy logic processor to process a measurement of the voltage and provide an information element representing the current. The device permits the precise use of semi-conductor or other components for the measurement of current in making a linear approximation of the current-voltage characteristics of the semi-conductors used by using triangular type membership functions. The linear approximation may also be combined with a Gaussian interpolation.
