A semiconductor device includes a substrate, a dielectric layer over the substrate, a first resistor element embedded within the dielectric layer, a second resistor element embedded within the dielectric layer, a first doped well within the substrate, the first doped well being aligned with the first resistor element, and a second doped well within the substrate, the second doped well being aligned with the second resistor element, the second doped well being non-contiguous with the first doped well.
