An integrated circuit having functional circuitry within a core portion of the integrated circuit. Input circuits are disposed on a first layer within a peripheral portion of the integrated circuit, where the input circuits are electrically connected to the functional circuitry. Power and ground buss lines are disposed on a second layer within the peripheral portion of the integrated circuit, where the second layer overlies the first layer. The power and ground buss lines overlie the input circuits, and are electrically connected to the input circuits. Bonding pads are disposed on a third layer within the peripheral portion of the integrated circuit, where the third layer overlies the second layer. The bonding pads overlie the power and ground buss lines and the input circuits, and are electrically connected to the input circuits.
