Optimization design method for configurable analog circuits and devices resulting from same. An implementation fabric for a given application domain can be accurately pre-characterized in terms of devices and parasitics. Customization structures are designed and characterized to be applied to the fabric to customize a device for a particular application. In some embodiments, characterization is accomplished by formulating a configurable design problem as an optimization with recourse problem, for example, a geometric programming with recourse (GPR) problem. Devices can be produced for multiple applications from the application domain using the same optimized fabric to provide predictable performance.
