1. A method, comprising:

  • receiving input signals to generate at least one output signal with a plurality of transistors, including transistors having gate lengths of less than one micron; and

    driving at least one signal with a driver circuit that includes at least one tipless transistor by replacing a first driver circuit that does not include tipless transistors with a second driver circuit that includes at least one tipless transistor, the at least one tipless transistor having source and drain vertical doping profiles without extension regions that extend in a lateral direction under a gate electrode, wherein the second driver circuit has a longer signal propagation delay than the first driver circuit.
