Abstract
Described examples include an integrated circuit having a plurality of nominally identical polycrystalline silicon resistors over a semiconductor substrate. Each of the polysilicon resistors has a resistor body with a first end and a second end, wherein the first end is connected to a current source and the second end is connected to a resistance discriminator. A first proper subset of the resistors have a first resistance, and a second first proper subset of the resistors have a difference second resistance.
