Abstract
An integrated analog circuit having a circuit topology and intrinsic characteristics which may be selected by digital control means is formed by batteries of similar circuit components arranged substantially in parallel or in a matrix array, anyone of which may be isolated or not by means of a dedicated integrated switch and by alternative interconnection paths among the different circuit components and/or batteries of circuit components, which may be also be selected by closing a relative integrated switch. A dedicated nonvolatile memory, integrated on the same chip may be permanently programmed and determine a certain configuration of all the integrated switches thus selected a particlar component or more components of each of said batteries of functionally similar components, and/or selecting a certain interconnection path among the different circuit components in order to form a functional integrated circuit having the desired topology and intrinsic characteristics. The integrated nonvolatile memory is programmed by means of a software program which may take as input data the desired values of the different parameters which determine the intrinsic characteristics of the functio…
