Patent abstract
A stacked inductor with different metal thickness and metal width. The stacked inductor comprises top and bottom metal traces which are aligned with each other. The thickness and width of the top and bottom metal traces are different. The top and bottom metal traces are connected at the end of metal trace with via holes. The inductance is increased with the use of the mutual inductance between top and bottom metal layers The parasitic resistor is reduced due to the difference of the top and bottom metal widths.
