Abstract
An embodiment of the present invention relates to a asynchronous interconnection system comprising a transmitter circuit and a receiver circuit inserted between inserted between respective first and second voltage references and having respective transmitter and receiver nodes coupled in a capacitive manner. The receiver circuit comprises: a recovery stage inserted between the first and second voltage references of the receiver circuit and connected to the receiver node; and a state control stage, in turn inserted between the first and second voltage references of the receiver circuit connected to the recovery stage correspondence with a first feedback node providing a first control signal and having a second feedback node connected in a feedback manner to the recovery stage. The recovery stage comprises a first feedback loop connected to the first feedback node and acting in such a way to recover a received voltage signal and a feedback loop connected to the second feedback node of the state control stage and acting in such a way to deactivate the recovery feedback on the receiver node and guarantee that the receiver node is let in a high impedance state.
