Abstract
An integrated circuit system, and a method of manufacture thereof, includes: an integrated circuit substrate; and a discretized tunable precision resistor having a total resistance including: a resistor body over the integrated circuit substrate, interconnects directly on the resistor body, metal taps directly on the interconnects and at opposing sides of the resistor body, and conductive metal strips over the interconnects, wherein the total resistance is a function of an active resistor length of the resistor body between a pair of the metal taps in contact with two of the conductive metal strips.
