  • Publication number: 20130272037
    Abstract: A power supply circuit for an electrical appliance, including a turning-on stage configured for determining a transition from a turned-off state, in which the power supply circuit is off and does not supply electric power, to a turned-on state of the power supply circuit. The turning-on stage includes a transducer of the remote-control type configured for triggering the transition in response to the reception of a wireless signal. In some embodiments, operating power is transmitted from a remote controller to a control circuit of the electronic equipment, such that the electronic equipment can be turned on remotely but draws zero standby power.

  • Publication number: 20130265017
    Abstract: An embodiment of a driving device is proposed for supplying at least one regulated global output current to a load. The driving device includes programming means for programming a value of the global output current within a global current range. Reference means are provided for supplying a reference voltage, which has a value corresponding to the value of the global output current. Conversion means are then used for converting the reference voltage into the global output current. The conversion means may further include a plurality of conversion units for corresponding partial current ranges, which partition the global current range.

In the driving device according to an embodiment of the disclosure, the conversion means include a plurality of conversion units for corresponding partial current ranges, which partition the global current range. Each conversion unit is adapted to convert the reference voltage into a partial output current that contributes to the global output current, with the partial output current that is within the corresponding partial current range.

  • Publication number: 20110234105
    Abstract: Driving a light-emitting element by a driver capable of testing at least an open or short condition of the light-emitting element. In particular, a driving signal is generated to drive the light-emitting element. It is evaluated based on the value of the driving signal whether a predetermined condition is reached. If so, a latch signal is output indicating that the testing has finished.

  • Patent number: 7154325
    Abstract: Variations in the actual resistance of a target poly resistor in a semiconductor integrated circuit can be compensated for by using an active circuit that provides a negative resistance in parallel with the target resistor. This produces a tuned resistance that is closer to a desired resistance than is the actual resistance of the target resistor.

  • Publication number: 20030001651
    Abstract: A programmable delay element comprises a plurality of delay modules (d, d′), which can be connected together for generating, starting from an input signal (IS), an output signal (OS) delayed with a pre-determined time-delay value referred to a given value (T) of operating period. A control logic (LC) selectively connects together the delay modules (d, d′) in such a way as to obtain the aforesaid pre-determined time-delay value. The arrangement is such that the jitter present on the delayed output signal (OS) is made to vary proportionally to the operating period (T) so as to maintain the ratio between said period (T) and said jitter substantially constant. The element is usable in particular in memories of the DDR-SDRAM type for generating the delayed DQS signal (DQS_delayed) with the possibility of varying selectively the amount of delay as a function of the frequency (T) of operation of the memory.
