Abstract
The effective parasitic end resistance of small-value precision integrated circuit resistors is reduced by providing N resistors connected in parallel and causing at least two of the resistors to share a terminal contact. The resulting integrated circuit resistor includes multiple terminal contacts of any number n greater than two. Of the n terminal contacts, N-1 terminal contacts are shared amongst said resistors. The parasitic end resistances are diminished by a factor equal to the number of resistors connected in parallel. By increasing the length of the active area of the N resistors by a factor equal to the number of the resistors, the desired resistance value remains undiminished. As a result, the parasitic end resistances may be made negligible compared to the desired resistance even for small value resistors.
