Full duplex digital isolator

A method of operating a circuit, the method comprising:

• providing a first transmitter circuit including a first input terminal and a first node;
• providing a first receiver circuit including a second node and a first output terminal;
• providing a second transmitter circuit including a second input terminal and the second node;
• providing a second receiver circuit including the first node and a second output terminal;
• receiving a first input data, by the first transmitter circuit;
• transmitting a first intermediate data, by the first transmitter circuit, corresponding to the first input data;
• receiving the first intermediate data, by the second receiver circuit;
• and
• producing a first output data, by the first receiver circuit, corresponding to the first input data.

A circuit comprising:

• a first transmitter circuit having a first input terminal arranged to receive first input data and a first node arranged to transmit a first intermediate data corresponding to the first input data;
• a first receiver circuit having a second node arranged to receive the first intermediate data and a first output terminal arranged to produce a first output data corresponding to the first input data;
• and
• a second transmitter circuit having a second input terminal arranged to receive a second input data and the second node, the second node further arranged to transmit a second intermediate data corresponding to the second input data.
