The present invention is directed to providing a generalized system and method for enabling circuit design and fabrication in the delta sigma domain. In accordance with exemplary embodiments, a framework for such a system is based on a library of generalized operators that can receive mulitple inputs, and that can be randomly chained together. Further, the operators are specifically configured to guarantee valid (e.g., bounded and/or stable) results, and to provide closure within the delta sigma domain. Linear operators are configured to provide closure by complying with a least two criteria: (1) with respect to linear operators, at least one of (a) the inputs and (b) the output of a portion of the operator used to implement a mathematical function is scaled (e.g., normalized) to guarantee valid results; and (2) outputs from each mathematical function are remodulated into a single bit stream in the delta sigma domain. Further, nonlinear operators such as mathematical operators, are configured with an eye toward producing valid results in the delta sigma region. |
