Claim:
1. A device comprising: a semiconductor substrate; a first constituent transistor comprising a first plurality of transistor structures in the semiconductor substrate connected in parallel with one another; and a second constituent transistor comprising a second plurality of transistor structures in the semiconductor substrate connected in parallel with one another; wherein the first and second constituent transistors are disposed laterally adjacent to one another and connected in parallel with one another; wherein each transistor structure of the first and second pluralities of transistor structures comprises a plurality of source regions and a plurality of body contact regions disposed in an alternating arrangement with the plurality of source regions along a lateral dimension of the device; and wherein each transistor structure of the first plurality of transistor structures has a lower resistance in a saturation region of operation than each transistor structure of the second plurality of transistor structures due to a layout difference in the alternating arrangement between the first and second pluralities of transistor structures.
