Abstract
The circuit generates an output value of an N-dimensional basis function. The circuit includes a string of sub-circuits, each sub-circuit computing a one-dimensional basis function. Each lower dimension sub-circuit is coupled to the adjacent higher dimension circuit, such that the current output is utilized as the input bias current to the adjacent higher dimension circuit. The coupling of sub-circuits in this manner provides the computation of the product of the 1-dimension basis functions produced by each of the sub-circuits.
