Abstract:
A type of wiring layout for pull-up and pull-down devices of an off-chip driver, comprising:a first bonding pad;a second bonding pad located next to the first bonding pad;a first pull-up driver on a lower side of the first bonding pad for providing a first pull-up voltage to the first bonding pad;a first pull-down driver on a right side of the first pull-up driver for providing a first pull-down voltage to the first bonding pad;a second pull-up driver on an upper side of the second bonding pad for providing a second pull-up voltage to the second bonding pad;a second pull-down driver on a left side of the second pull-up driver for providing a second pull-down voltage to the second bonding pad;a first pull-up signal line at a lower side of the first pull-up driver, wherein through a first pull-up conductive wire, the first pull-up signal line is connected to the first pull-up driver for providing the first pull-up voltage to active devices inside the first pull-up driver so that the first pull-up driver is pulled to a first high potential;a first pull-down signal line at a lower side of the first pull-down driver, wherein through a first pull-down conductive wire, the first pull-down signal line is connected to the first pull-down driver for providing the first pull-down voltage to active devices inside the first pull-down driver so that the first pull-down driver is pulled to a first low potential;a second pull-up signal line at an upper side of the second pull-up driver, wherein through a second pull-up conductive wire, the second pull-up signal line is connected to the second pull-up driver for providing the second pull-up voltage to active devices inside the second pull-up driver so that the second pull-up driver is pulled to a second high potential; anda second pull-down signal line at the upper side of the second pull-down driver, wherein through a second pull-down conductive wire, the second pull-down signal line is connected to the second pull-down driver for providing the second pull-down voltage to active devices inside the second pull-down driver so that the second pull-down driver is pulled to a second low potential.
