Abstract
An electronic circuit, including an equalizer circuit to input a differential signal, a rectifier circuit to receive the differential signal and output a first current and a second current, a replica circuit to receive a differential threshold signal and output a third current and a fourth current to compensate for PVT variations in the first and second currents, and a comparator circuit configured to compare a differential voltage generated based on the first, second, third, and fourth currents to determine a loss of signal event of the electronic circuit.
