Low-swing signaling scheme for data communication

An input/output (I/O) interface circuit, the I/O interface circuit including a plurality of receivers, each of at least a subset of the receivers being adapted to receive an input signal having a first voltage swing and to generate an output signal having a second voltage swing, the second voltage swing being greater than the first voltage swing, at least one of the receivers comprising:

• at least one sense amplifier, the at least one sense amplifier comprising:
• a first transistor of a first conductivity type, the first transistor having a first source/drain adapted for connection with a first voltage supply, a gate adapted for receiving a first control signal, and a second source/drain;
• a second transistor of a second conductivity type, the second transistor having a first source/drain adapted for connection with a second voltage supply, a second source/drain connected to the second source/drain of the first transistor and forming a first output of the sense amplifier, and a gate adapted for connection with a second control signal via a capacitive element;
• and
• a switching circuit operative to selectively couple the input signal with the gate of the second transistor as a function of a third control signal, the third control signal being indicative of a voltage generated at the first output of the sense amplifier;
• wherein the sense amplifier is operative in a first mode to store charge in the capacitive element, and is operative in a second mode to impart a voltage on the gate of the second transistor which is indicative of the charge stored in the capacitive element.
