Abstract
Physical layouts of ratioed circuit elements, such as transistors, are disclosed. Such layouts can maintain electrical characteristics of the ratioed circuit elements relative to one another in the presence of mechanical stresses applied to an integrated circuit, such as an integrated circuit encapsulated in plastic. The ratioed circuit elements can include first and second composite circuit elements formed of first and second groups of circuit elements, respectively, arranged around a center point. The first group of circuit elements can be arranged on a grid and the second group of circuit elements can include four circuit elements spaced approximately the same distance from the center point. Each of the circuit elements in the second group can be off the grid in at least one dimension. The first and second groups of circuit elements can be arranged around a perimeter of dummy circuit elements in some embodiments.
