An ESD protection circuit design incorporating a single, or a plurality of, parallel inductor and capacitor, also known as LC tank(s), to avoid power loss by parasitic capacitance in ESD circuits. The first design described incorporates a LC tank structure. The second includes two LC tank structures. These structures can be expanded to form ESD protection circuit structures stacked with n-stages LC tanks. The last design described is ESD protection circuits formed by stacking the first design. These designs can avoid power gain loss from parasitic capacitance of ESD, because the parameters of LC tank can be designed to resonant at a desired operating frequency. Each of these designs can be altered slightly to create variant designs with equal identical ESD protection capabilities.
An electrostatic discharge (ESD) circuit, adaptive to a radio frequency (RF) device, which includes a RF circuit with a VDD voltage RF pad, a VSS RF pad and a RF input pad, the ESD circuit comprising:
