Abstract: An integrated circuit includes an overvoltage protection circuit. The overvoltage protection circuit detects overvoltage events at a pad of the integrated circuit. The overvoltage protection circuit generates a max voltage signal that is the greater of the voltage at the pad and a supply voltage of the integrated circuit. The overvoltage protection circuit disables a PMOS transistor coupled to the pad by supplying the max voltage signal to the gate of the PMOS transistor when an overvoltage event is present at the pad.

Abstract: A method for smoothing current consumed by an electronic device is based on a series of current copying operations and on a current source delivering a reference current. The reference current is delivered in such a manner that current consumed as seen from the power supply depends on the reference current.

Abstract: An electrostatic discharge protection circuit is coupled to a power supply rail and a ground supply rail of an integrated circuit and includes at least one shunt configured to couple the supply rails and a trigger configured to supply on an output a shunt control voltage to a control terminal of the shunt to set the shunt in a coupling state when an ESD event is sensed on one of the supply rails. The protection circuit further comprises a voltage booster arranged between the output of the trigger and the control terminal of the shunt to boost the shunt control voltage.

Abstract: An integrated circuit includes a voltage regulating circuit in the form of only one transistor, or a group of several transistors in parallel, that are connected between first and second terminals configured to be coupled to an antenna. A control circuit operates to make the voltage regulating circuit inactive when a pulse generated by an electrostatic discharge event appears at one of the first and second terminals, regardless of the direction of flow of the pulse between the first and second terminals. An electrostatic discharge circuit is further provided to address the electrostatic discharge event.
