Abstract
A low-swing receiver includes a sense amplifier including a first transistor having a source connected with a first voltage supply and a gate for receiving a control signal, and a second transistor having a source connected with a second voltage supply, a drain connected to a drain of the first transistor, and a gate coupled to a second control signal via a capacitive element. A switching circuit is operative to selectively couple an input signal supplied to the sense amplifier with the gate of the second transistor as a function of a signal generated at an output of the sense amplifier. 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.
