    摘要： In the field of systems for the synchronization of modular electronic circuits, a system is provided for the coordinated activation of the modules. This system includes synchronization cells that have their pace set by a primary clock signal and deliver secondary clock signals controlled intermittently by the enabling signals to respectively activate the modules. The cells lock the state of each enabling signal associated with a regulator for regulating the periodicity of the change in state of each secondary clock signal and coordinating the changes in states of the secondary clock signals with one another. The system can be advantageously applied to electronic circuits having very high frequency data processing modules, especially those providing for the multiplexing of the transmissions of data carried out by each module.

    摘要： A circuit for the filtering of a pulse signal comprises means to detect an output pulse upon the detection of an input pulse, the shape of this output pulse being based on elementary delays obtained by the charging and discharging of capacitors. During the generation of the output pulse, no new input pulse can be taken into account.

    摘要： A voltage booster circuit including an input for receiving a supply voltage, a plurality of stages for producing an output voltage from the supply voltage by the transfer of charges between at least two of the plurality of stages, and circuit for coupling and decoupling stages to vary the number of stages operatively connected together. A method for producing an output voltage from a supply voltage by using a voltage booster circuit, the circuit includes an input for receiving the supply voltage, a plurality of stages, and a selection switch for the selective isolation of the stages or for the selective connection of the stage. The method includes the following steps: starting the circuit; comparing the value of the output voltage with a decrementation threshold; and decreasing the number of stages which are connected if the decrementation threshold is reached by the value of the output voltage.

    摘要： A voltage reference generator includes a voltage source and a differential amplifier. The voltage source supplies a stable voltage reference to a positive input of the differential amplifier which is configured as a follower having its output looped back to its negative input. The negative feedback loop is a variable-resistance loop that is controlled by the output of the differential amplifier. The variable-resistance feedback loop transiently imposes open-loop operation when the voltage reference generator is turned on so as to provide high current to the output before imposing closed-loop operation in follower mode.
