Abstract:
1. A protection apparatus for protecting an integrated circuit against electrostatic discharges (ESD), said integrated circuit including a radiofrequency or higher frequency internal circuit having a resistance component and first and second terminals for a radiofrequency or higher frequency signal, the protection apparatus comprising: an ESD protection circuit configured to electrically couple said first and second terminals of the internal circuit to at least a first pad, said ESD protection circuit including a resistive component; first and second ESD protection devices coupled to first and second supply lines, said first and second ESD protection devices having first and second parasitic capacitive components, respectively; connection circuitry configured to connect said ESD protection circuit and said first and second ESD protection devices to a first common circuital point and prevent the resistive component of said ESD protection circuit or said internal circuit from combining with parasitic capacitive components of said first and second ESD protection devices.
