Flexible multimode logic element for use in a configurable mixed-logic signal distribution path

A path in an integrated circuit comprising:

• a multi-mode dynamically selectable circuit including:
• a first signal input;
• a first signal output;
• and
• one or more control inputs, said multi-mode dynamically selectable circuit being configured to dynamically switch among the following operating modes:
• a full-swing mode, a limited-swing mode, a full-swing to limited-swing converter mode, and a limited-swing to full-swing converter mode;
• and
• a mode controller in electrical communication with said multi-mode dynamically selectable circuit, said controller for providing information representing a selection for said operating mode to said multi-mode dynamically selectable circuit.

A selectable-mode circuit, comprising:

• a first signal input;
• a first signal output;
• one or more control bit inputs;
• an adjustable bias voltage input;
• and
• a means for dynamically switching the operating mode of the circuit among the following operating modes:
• a full-swing mode, a limited-swing mode, a full-swing to limited-swing converter mode, and a limited-swing to full-swing converter mode.
