Abstract

This invention discloses a resistance balance circuit including: at least two electronic components aligned in a row matrix, connected to one another in parallel, thereby forming a row matrix structure; an input end disposed at one end of the row matrix structure and configured for entry of current passing the electronic components in the row matrix structure; and an output end disposed diagonally opposite to the input end in the row matrix structure and configured for exit of the current passing the electronic components in the row matrix structure, wherein routes for the current passing the electronic components from the input end to the output end are equal in length, and thus the same current passes the electronic components in the matrix structure.
