Abstract
A method of controlling a current flowing through a load including the steps of: applying a first transfer function representative of the load to a first voltage to obtain a second voltage; applying the second voltage to a first terminal of a circuit for generating the current; sampling a third voltage between first and second terminals of the load; comparing the third voltage with the second voltage; and determining the current to be supplied to the load according to the result of the comparison.
