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

Abstract

A receiver circuit receives a differential signal that includes positive and negative spikes, and produces an output signal as a function of the differential signal. A first comparator produces an intermediate set signal that includes a pulse at each positive spike of the differential signal, and a second comparator produces an intermediate reset signal that includes a pulse at each negative spike of the differential signal. A logic circuit detects whether the digital signal switches between a first value and a second value, and whether the intermediate reset signal and the intermediate set signal include pulses lasting longer than a threshold. The logic produces a set correction signal and a reset correction signal. The logic circuit produces a corrected set signal and a corrected reset signal. An output circuit produces an output signal based on the corrected set signal and the corrected reset signal.
