Abstract
A method has been disclosed that relates to electrical variability compensation technique for configurable-output circuits. The compensation technique can be applied to a generality of circuits whose output has to vary between two electrical limits spanning the range in between them according to a specific code given as input. A switching sequence that is process gradient-direction agnostic has been disclosed which limits variability. An electric device comprising a processing gradient-direction agnostic configurable-output circuit has been also disclosed.

A method for compensating variabilities of an electrical device in configurable output circuits, comprising:
- coupling a first set of electric components to a common node;
- coupling a second set of electric components to the common node;
- selecting and interconnecting some electric components of the first set to a first reference voltage and some electric components of the second set to a second reference voltage to provide a variable output value at the common node between the second reference voltage and the first reference voltage based on a configuration;
- and
- implementing an interconnecting sequence of respective electric components in the first set and the second set based on an intrinsic characteristic of the respective electric components and according to an agnostic gradient direction of a physical topographical location of the respective electric components.
A method for compensating variabilities of an electrical device in configurable output circuits comprising:

- identifying in said matrix a plurality of surrounding circles of cells having increasing radius starting from a central core of the matrix including a first group of cells;
- and
- selecting and interconnecting electric components represented in the matrix according to an interconnecting sequence based on an agnostic gradient direction of a physical topographical location of the electric components.
An electrical device including a plurality of electric components realized on a semiconductor substrate and having an intrinsic characteristic, comprising:
- a first subset of said electric components coupled to a common node, the common node configured to provide an output;
- and
- a second subset of said electric components coupled to the common node;
- wherein said electric components are configured to be interconnected to a first reference voltage or to a second reference voltage according to a sequence based on an agnostic gradient direction of a physical topographical location of the electric components.
