An apparatus and method is disclosed for a limited swing line driver. A driver circuit generates a voltage that is transmitted to a unity gain voltage amplifier and a common source amplifier. A source-follower circuit in the voltage amplifier is activated when the voltage reaches a voltage threshold for an activating transistor, sending voltage to the output of the common-source amplifier, resulting in an output with a reduced swing. In an alternate embodiment, a variable-level reduced swing line driver is disclosed that uses a transistor as a variable resister to alter the threshold voltages and level control. A level control circuit is further disclosed that controls one or more variable-level line drivers.
