Calculate the resistor parameters given sheet resistance and width of the resistor in semiconductor technology

Calculating the resistor parameters ( length, width resistance etc.) is a common task done by IC designers when a chip is designed. This post introduces a simple Javascript calculator that calculates the length of a resistor, given the sheet resistance of the technology, the required resistance and the width of the design rule for resistors. This calculator provides a starting point quickly to do the calculation. It is the first order value of the resistance. Please download the calculator from the SPG website to use it.
