Claim Text:
1. An integrated circuit (IC) electromagnetic interference (EMI) filter with electrostatic discharge (ESD) protection incorporating inductor-capacitor (LC) resonance tanks, said IC EMI filter comprising: a first diode with a first anode thereof coupled to a ground, wherein said first diode comprises a first parasitic capacitance between a first cathode of said first diode and said first anode; a first inductor having a first series resistance, and being coupled to said first cathode; a second diode with a second anode thereof coupled to said ground, wherein said second diode comprises a second parasitic capacitance between a second cathode of said second diode and said second anode; a second inductor having a second series resistance, and being coupled to said second cathode; and a first passive element coupled between said first and second inductors, wherein a first node between said first passive element and said first inductor is coupled to a first port, and a second node between said first passive element and said second inductor is coupled to a second port.
