Low voltage signaling

A low voltage signaling system for integrated circuits, comprising:

• a first voltage domain operating at a nominal integrated circuit (IC) power supply voltage (Vdd) swing level at a signal transmitting end of a first chip, the first voltage domain including a switched capacitor converter on-chip supply voltage generation unit for generating one or more reduced voltage levels with respect to Vdd, and a level-shifting driver in communication with the on-chip voltage supply generation unit and a first input signal, the level-shifting driver outputting a converted first input signal to a reduced voltage swing level with respect to the first voltage domain;
• a second voltage domain having one or more transmission interconnect lines operating at the reduced voltage swing level;
• and
• a sense amplifier in a third voltage domain at a signal receiving end of a second chip, the third voltage domain operating at the Vdd swing level, wherein the sense amplifier senses the down converted first input signal transmitted over the second voltage domain and generates a first output signal operating back up at the Vdd swing level.
