ABSTRACT:
A method is disclosed for matching the sensitivities of different-sized resistors to changes in resistance due to changes in width resulting from a systematic manufacturing error. In order to produce sets of resistors which can be deployed in predetermined ratios of resistance, the sensitivities of a matching resistor and a reference resistor are equalized by forming the matching resistor as a plurality of parallel strips as opposed to a unitary rectangular section.
