Configuration method and device for electrical and/or electronic circuits

A method for configuring an electrical circuit comprising several functional blocks each having an output characteristic, the electrical circuit having a performance parameter which is dependent on the output characteristics of the functional blocks being mutually proportional in value, the method comprising:

• providing a set of electrical elements each having the same theoretical nominal value but different true values;
• providing a plurality of connecting elements configured to connect said set of electrical elements to at least one of:
• one another and the rest of the electrical circuit according to a plurality of different connection configurations to be tested;
• connecting said set of electrical elements into each of said plurality of different connection configurations to form at least a pair of said functional blocks such that for each configuration at least part of the electrical elements in said set of electrical elements are distributed between said pair of functional blocks;
• measuring said performance parameter of the electrical circuit for each of said plurality of different connection configurations;
• determining, based on said performance parameter, a mismatch between the output characteristics of the pair of functional blocks for each of the plurality of connection configurations, each mismatch caused by said different true values;
• identifying a smallest mismatch between said output characteristics of the pair of functional blocks among the plurality of connection configurations;
• and
• positioning the connecting elements to form a connection configuration of the set of electrical elements which provides the pair of functional blocks having smallest mismatch.
