A method includes selectively degrading a current capacity of a first finned-field-effect-transistor (finFET) relative to a second finFET by forming a material on a fin of the first finFET to increase a current resistance of the first finFET. The second finFET is electrically connected to the first finFET in a circuit such that a current flow through the second finFET is a multiple of a current flow through the first finFET.
