Trimming of operative parameters in electronic devices based on corrections mappings

摘要

An electronic device (100) having a plurality of operative parameters (S(i)) is provided. The electronic device includes means (200; 500) for applying a plurality of trimming actions (TA(i)) to each parameter for causing a corresponding correction of the parameter, for at least one reference parameter (S(r); S(rl), S(r2)), means (120) for measuring the reference parameter responsive to the application of at least part of the trimming actions (TA(r); TA(r1), TA(r2)) to select one of the trimming actions providing a target value of the reference parameter, and means (M(r), D(r), TC(r); M(r1), D(r1), TC(r1), M(r2), D(r2), TC(r2)) for forcing the application of the selected trimming action for the reference parameter. For each non-reference parameter (S(o)) different from the at least one reference parameter, the electronic device includes means (CV(o); CV'(o)) for selecting one of the trimming actions (TA(o)) for the non-reference parameter corresponding to the selected trimming action (TA(r); TA(r1), TA(r2)) for the at least one reference parameter according to a predetermined mapping of each group of multiple corrections of the at least one reference parameter on a single correction of the non-reference parameter, and means (D(o), TC(o)) for forcing the application of the selected trimming action for each non-reference parameter.
