Abstract
In the laser trimming of passive circuit elements such as resistors, capacitors and inductors, various trimming parameters must be selected. To select a element is compared with a target value for the parameter to determine an offset value between the measured parameter value and the target value. The relevant trim parameters are then selected based on the determined offset values.
