Claim Text:
1. An apparatus comprising an integrated circuit, the apparatus comprising: a first node configured to carry a signal; a second node configured to carry a voltage reference; a first voltage clamp of the integrated circuit, the first voltage clamp having an anode and a cathode, wherein a first parasitic capacitance associated with the anode and junction capacitance of the first voltage clamp is less than a second parasitic capacitance associated with the cathode and substrate capacitance of the first voltage clamp, wherein the anode is operatively coupled to the first node, and the cathode is operatively coupled to the second node, the first voltage clamp comprising at least a first rectifier; and a second voltage clamp of the integrated circuit, the second voltage clamp having an anode and a cathode, wherein a third parasitic capacitance associated with the cathode and junction capacitance of the second voltage clamp is less than a fourth parasitic capacitance associated with the anode and substrate capacitance of the second voltage clamp, wherein the anode is operatively coupled to the second node, and the cathode is operatively coupled to the first node, the second voltage clamp comprising at least a second rectifier.
