A conducting path with a path meander provides a precision voltage-dividing circuit. At each location wherein a voltage level is to be established, the conducting path has an expanded region called a junction region. The centers of all junction regions are equidistant from the centers of neighboring junction regions. Junction regions are positioned at predetermined intervals along the straight portions of the conducting path and at each corner of the path meander. Each junction region has a metal patch extending therefrom. The metal patches are coupled to conducting plugs that, in turn, can be coupled to switching elements of a digital-to-analog converter unit. The junction regions can be altered to increase the precision of the voltage-dividing circuit. Because the junction regions are equidistant from the neighboring junction regions, a cell that includes the switching elements can have a square geometry.
A voltage-dividing network for use with an integrated circuit, said voltage-dividing circuit comprising:
A method for providing an equal resistance between a multiplicity of locations on a conducting path, said conducting path having straight portions connected by corner portions, said method comprising the steps of:
A path of conducting material for providing a series of equal resistances between preselected locations along said conducting path, said path having straight portions and corner portions;
