An integrated circuit includes a substrate layer and a resistor bank in a polysilicon layer disposed on the substrate layer. The resistor bank includes a plurality of resistor elements having a body portion extending in a longitudinal direction. A metal line is disposed in a metal layer above the polysilicon layer to extend transverse to the longitudinal direction and across the body portion of a group of the plurality of resistor elements, thereby forming a first region of the resistor bank and a second region of the resistor bank. The first region is separated from the second region by the metal line. A resistor device having a predetermined resistance includes a subset of the resistor elements in the group electrically coupled together in the second region. The resistor device also includes first and second terminals located in the same first or second region of the resistor bank.

An integrated circuit including first and second macroblocks arranged in a first direction, and a plurality of cells between the first macroblock and the second macroblock, the plurality of cells including at least one first ending cell adjacent to the first macroblock and having a first width in the first direction, at least one second ending cell adjacent to the second macroblock and having a second width different from the first width in the first direction, and at least one standard cell between the at least one first ending cell and the at least one second ending cell may be provided.
