Title:
METHOD AND DEVICE FOR PROTECTING AN INTEGRATED CIRCUIT AGAINST ELECTROSTATIC DISCHARGES
Document Type and Number:
WIPO Patent Application WO/2021/001740
Kind Code:
A1
Abstract:
The invention concerns a method for protecting an input or input/output terminal (P) of an integrated circuit (IC1) against electrostatic discharges, the method comprising steps consisting in: generating a control signal (CS) resulting from a comparison of a voltage at the terminal (P) with a threshold voltage, the terminal being insulated from a supply voltage of the integrated circuit, closing a switch (N3) between the terminal and ground if the control signal indicates that the terminal voltage is higher than the threshold voltage, and providing a component (CRC) connected between the terminal and the switch, for lowering an equivalent capacitance of the integrated circuit, seen from the terminal.
