Abstract:
A library of cells for designing an integrated circuit, the library comprises continuous diffusion compatible (CDC) cells. A CDC cell includes a p-doped diffusion region electrically connected to a supply rail and continuous from the left edge to the right edge of the CDC cell; a first polysilicon gate disposed above the p-doped diffusion region and electrically connected to the p-doped diffusion region; an n-doped diffusion region electrically connected to a ground rail and continuous from the left edge to the right edge; a second polysilicon gate disposed above the n-doped diffusion region and electrically connected to the n-doped diffusion region; a left floating polysilicon gate disposed over the p-doped and n-doped diffusion regions and proximal to the left edge; and a right floating polysilicon gate disposed over the p-doped and n-doped diffusion regions and proximal to the right edge.
