Abstract
A long channel transistor and a shorter channel transistor operate in conjunction to drive an output node. The long channel device is first activated by a drive signal and the drive signal is input to a delay element that then activates the shorter channel device. By enabling the long channel device first, hot carrier injection effects are reduced. Employing two transistors that are sized to operate in different voltage ranges reduces surge current. The two-transistor configuration of the present invention occupies less area than a single long channel device with similar drive capabilities.
