ABSTRACT:
A method for manufacturing a self-compensating resistor within an integrated circuit is disclosed. The self-compensating resistor includes a first resistor and a second resistor. The first resistor having a first resistance value is initially formed, and then the second resistor having a second resistance value is subsequently formed. The second resistor is connected in series with the first resistor. The second resistance value is less than the first resistance value, but the total resistance value of the first and second resistors lies beyond a desired target resistance range. Finally, an electric current is sent to the second resistor to change the dimension of the second resistor such that the total resistance value of the first and second resistors falls within the desired target resistance range.
