Abstract
There is described a protection apparatus against electrostatic discharges for an integrated circuit; said integrated circuit comprises a radiofrequency or higher frequencies internal circuit. The internal circuit has a first and a second terminals for the output or the input of a radiofrequency or higher frequencies signal. The apparatus comprises first means for electrically connecting said first and second terminals of the internal circuit to at least a PAD and the integrated circuit comprises at least a first and a second supply circuital lines and at least a first and a second protection devices against electrostatic discharges connected to said first and second supply lines. First means have a resistive component and each of said first and second protection devices against the electrostatic discharges have a parasitic capacitive component. The apparatus comprises second means configured to connect said first means and said first and second protection devices against the electrostatic discharges to at least a common circuital point preventing the resistive component of said first means or said internal circuit from combining with the parasitic capacitive components of said first and second protection devices against the electrostatic discharges.
