Claim 18:
19. The method of claim 18, further comprising:
receiving a second ESD voltage on the first node, the second ESD voltage being greater than a reference supply voltage of a reference voltage supply, the second ESD voltage corresponding to a second ESD event;
turning on a second diode, thereby conducting a second ESD current from a second anode of the second diode to a second cathode of the second diode;
conducting the second ESD current from the second cathode of the second diode to the second signal tap of the ESD clamp circuit; and
discharging the second ESD current of the second ESD event by the ESD clamp circuit.
