1. A design structure embodied in a machine readable medium that is executable on a computer to design, manufacture, or test an integrated circuit, the design structure comprising:
a current mirror comprising N stages, each stage comprising 2n−1 dual gate transistors where N is a positive integer equal to or greater than one and n is an integer between 0 and N−1 for each of said N-stages, values of n being different for each of said N stages;
an output, every dual gate transistor of each stage of said N stages connected to said output;
N inputs, each input of said N inputs connected to a different and respective stage of said N stages, any particular input of said N inputs connected to every dual gate transistor of a stage to which said particular input is connected to; and
a current reference circuit, comprising a reference current source and a reference dual gate transistor, each stage of said N stages connected to said current reference circuit.
