    Abstract: A video and/or audio decoder provided with a first terminal for supplying an analog audio and/or video signal, including: a first circuit capable of supplying a digital signal which is an image of said analog signal; a digital-to-analog converter capable of receiving as an input said digital signal; an amplifier coupling a second output terminal of the digital-to-analog converter to the first terminal; and a second circuit capable of comparing a signal representative of the voltage or current level on the first terminal with a reference signal, and of deducing therefrom whether the first terminal is connected or not to an analog input terminal of a video signal display and/or audio signal playing device.

    Abstract: A diode control device include a first terminal for receiving a first power supply voltage and a second terminal for receiving a second power supply voltage. A circuit of the diode control device applies a regulated voltage on the anode of the diode in response to a control voltage. The control voltage is equal to a preset voltage when a reference voltage is less than or equal to zero. Conversely, when the reference voltage is greater than zero, the control voltage is equal to the sum of the present voltage and a difference between cathode voltage of the diode and the reference voltage.

    Abstract: A charge-pump device receives two complementary driving signals and a DC signal that are applied to a charge-pump stage containing a full-wave rectifier bridge configured to deliver a DC output signal. The bridge includes active switches controllable by control signals present at two control nodes. The charge-pump device further receives complementary auxiliary signals that are respectively synchronous with the complementary driving signals but have faster edges. Two resistive capacitive filters filter the complementary auxiliary signals to generate control signals at the two control nodes for controlling actuation of the active switches in the bridge.
