Abstract
A network comprises an arrangement of regular structures and merged structures, in which the regular structures each comprise one or more mutually identical fixed elements and an equal number of adjustable elements of equal value, and the adjustable elements each comprising two or more adjustable units. The regular structures may comprise one or more mutually identical fixed elements and an equal number of adjustable elements of equal value. The adjustable elements each comprise two or more adjustable units, and the merged structures comprise N mutually identical fixed elements and one merged adjustable element. The merged adjustable elements have substantially the same value as that of N adjustable elements, where N is an integer equal to or greater than 2, and the merged elements each may comprise one or more adjustable units. The network accordingly is trimmable in a manner that uses minimum area and consumes minimum time during manufacture. A described application is in digital-to-analog converter trim circuitry.
