  • Patent number: 5619153
    Abstract: A pullup circuit having a limited voltage swing and fast pullup and pulldown times comprises a pullup structure, a pulldown structure and an internal node. The pullup circuit operates to limit the current of the pullup structure before the N-tree discharges the internal node, thereby reducing the pullup effect of the pullup structure to reduce fall time and power consumption. Then the pullup circuit maximizes the current of the pullup structure after the N-tree has pulled down the internal node to increase the pullup effect of the pullup structure to reduce rise time. As a result, the voltage of the internal node both charges more quickly when the N-tree becomes inactive and discharges more quickly when the N-tree becomes active.
