Abstract

An integrated circuit having a passive circuit component that can be adjusted following the manufacturing process to provide a precise absolute value for resistance or capacitance. A plurality of passive elements are selectively combinable using logic gates to include or exclude each element from a network, wherein the combined value of the included passive elements equals the value of the passive circuit component. The logic gates are set by outputs from a decoder to reduce the required inputs to the chip.
