发明名称 Multi-concentric pad arrangements for integrated circuit pads
摘要 Multi-concentric pad (MCP) arrangements provide for increased pad densities on integrated circuits. The multi-concentric pad (MCP) configuration includes a first set of input output (IO) pads and a second set of IO pads, both disposed on an integrated circuit die. Each IO pad in said first set and said second set of IO pads includes a bond pad for receiving a bond wire connection, and an IO circuit coupled to the bond pad. The IO circuits provide an interface between a signal received at the corresponding bond pad and a core circuit disposed on said IC die. The first set of IO pads are arranged closer to the perimeter of the IC die than the second set of IO pads. Furthermore, the second set of IO pads are arranged so that each IO circuit in the second set of IO pads is closer to the center of the IC die than a corresponding IO circuit in the first set of IO pads.
