    Abstract: A device includes a first connection pin, a second connection pin, a third connection pin, and a fourth connection pin. The second connection pin is configured to be connected to a supply voltage. The fourth connection pin is configured to be coupled to a reference voltage. The device further includes a first transistor including: a first gate and a first source/drain coupled to the first connection pin; a second transistor including a second gate and a second source/drain connected to the first transistor; and a third transistor including a third gate, a third source/drain connected to the second transistor, and a fourth source/drain connected to the fourth connection pin. The third transistor is configured to be controlled by a digital signal using the third connection pin. Both the first gate and the second gate are directly connected to the second connection pin.

    Abstract: An electronic chip includes a chip core including an input terminal, an output terminal, an external pad, and an input-output circuit coupled to the chip core and the external pad. The input-output circuit includes an enable terminal coupled to the chip core, a connection terminal coupled to the external pad, a switchable diode device coupled between a supply voltage and a reference voltage, and a levelling circuit. The switchable diode device is coupled to the connection terminal and the enable terminal and is configured to operate as a diode in response to a control signal in a first state applied to the enable terminal and to operate as an open circuit in response to the control signal in a second state applied to the enable terminal. The levelling circuit is coupled to the connection terminal, the input terminal of the chip core, and the output terminal of the chip core.

    Abstract: An integrated circuit includes peripheral conductive pads interconnected by a peripheral conductive track within an integrated circuit chip. The integrated circuit chip further includes internal conductive pads interconnected by an internal conductive track within the integrated circuit chip. A conductive bonding wire external to the integrated circuit chip connects the one peripheral conductive pad to one internal conductive pad. A package encapsulates the integrated circuit chip and the conductive bonding wire.
