摘要： A high voltage generator of the DAC-controlled type, has an input terminal connected to a first voltage reference and an output terminal providing an output voltage and comprises at least a voltage control circuit and a charge pump circuit inserted, in series to each other, between the input and output terminals of the high voltage generator, and an output regulator connected to the output terminal of the high voltage generator and comprising at least a digital-to-analog converter or DAC. The output regulator further comprises at least an additional current regulation portion connected to the output terminal of the high voltage generator through a first resistive element of the output regulator as well to an enabling terminal which provides an enabling signal, the additional current regulation portion being supplied by a second voltage reference having a voltage level higher than a voltage level of the first voltage reference.

摘要： A voltage booster for generating a boosted voltage, including a charge pump adapted to generate the boosted voltage starting from a supply voltage by a transfer of electric charge controlled by at least one oscillating signal having an oscillation frequency; an oscillator for providing the oscillating signal; and a regulation circuit arranged to receive and perform a comparison of a voltage related to the boosted voltage and a reference voltage, and adapted to provide at least one regulation signal indicative of a result of said comparison, wherein said regulation signal is fed to the oscillator to control said oscillation frequency. The regulation circuit is adapted to cause the at least one regulation signal take one among a plurality of discrete values, depending on the result of the comparison, so that the oscillation frequency of the at least one periodical signal accordingly can take one among a plurality of discrete oscillation frequency values.
