Abstract
A composite digital network including an integrating circuit, a summing circuit and a coefficient circuit is formed as an integrated circuit that provides a selected one of digital arithmetic circuits that perform different arithmetic operations depending upon coefficients of the coefficient circuits. A plurality of units of such composite digital networks may be connected in rows, columns or layers to provide an expanded network. In a method of producing such a composite digital network, basic digital arithmetic circuits that respectively correspond to various types of basic analog arithmetic circuits are defined based on Kirchhoff's rules, for example, and these basic digital arithmetic circuits are coupled to each other via a coefficient circuit to thus provide a generic digital arithmetic integrated circuit.
