Receiver circuit, corresponding isolated driver device, electronic system and method of decoding a differential signal into a digital output signal

A method of decoding a differential signal into a digital output signal, the method comprising:

• receiving the differential signal;
• producing an intermediate set signal based on the differential signal;
• producing an intermediate reset signal based on the differential signal;
• producing a set correction signal based on the digital output signal and the intermediate reset signal;
• producing a corrected set signal based on the intermediate set signal and the set correction signal;
• producing a reset correction signal based on the digital output signal and the intermediate set signal;
• producing a corrected reset signal based on the intermediate reset signal and the reset correction signal;
• and
• producing the digital output signal based on the corrected set signal and corrected reset signal;
• asserting the digital output signal in response to a pulse being detected in the corrected set signal and de-asserting the digital output signal in response to a pulse being detected in the corrected reset signal.

A receiver circuit, comprising:

• a differential input including a first input node and a second input node;
• a first comparator circuit having an inverting input coupled to the first input node and a non-inverting input coupled to the second input node;
• a second comparator circuit having an inverting input coupled to the second input node and a non-inverting input coupled to the first input node;
• a logic circuit having a first input coupled to an output of the first comparator a second input coupled to an output of the second comparator;
• and
• a flip-flop having a first input coupled to a first output of the logic circuit, a second input coupled to a second output of the logic circuit, and an output terminal, wherein the logic circuit includes a third input coupled to the output of the flip-flop.
