Dynamic hysteresis circuit

An apparatus comprising:

• first circuitry for detecting a transition of a data signal comprising a data packet received at a circuit while the circuit is in a first hysteresis mode;
• second circuitry for placing the circuit in a second hysteresis mode subsequent to the detecting;
• and
• third circuitry for returning the circuit to the first hysteresis mode subsequent to completion of receipt of the data packet to await a next data packet;
• wherein the circuit comprises a comparator and wherein the placing the circuit in the second hysteresis mode comprises dynamically increasing a number of devices comprising a feedback circuit of the comparator.
