Abstract
An integrated circuit has an output buffer circuit for driving voltage state transitions of a transmission line. An output transistor has a gate terminal for controlling an output voltage of the output transistor, which is applied at an output terminal to the transmission line. (A voltage state transition comprises changing the output voltage from a first state voltage to a second state voltage.) An impulse current driver injects charge into the gate terminal during an impulse phase at the beginning of the voltage state transition to rapidly bring the output transistor through its dead zone to the threshold of its active region. A slewing current driver provides a comparatively limited current to the gate terminal after the impulse phase to cause the output transistor to complete a substantially smooth voltage state transition.
