Abstract
A resistor having a novel physical geometry is provided. The physical geometry of the resistor minimizes the current paths through the resistor such that the reactance components of the resistor is minimized for radio frequency operation. The resistor is made from a resistive material such as chrome silicon oxide, nichrome. The physical geometry of the resistor layout reduces the physical area occupied by the resistor, and also results in lower sensitivity to a DC trimming procedure used in the manufacturing process.
