Abstract: A voltage regulator with quick response includes: an output terminal supplying a regulated voltage; and at least a first boost circuit, controlled for alternately accumulating a first charge in a first operating condition and supplying the first charge to the output terminal in a second operating condition. In addition, the first boost circuit is provided with a compensation stage supplying the output terminal with a second charge substantially equal to the first charge, when the first boost circuit is in the first operating condition.

Abstract: An output buffer device having first and second supply voltage references, the first voltage reference being lower in value than the second voltage reference. The output buffer device includes first and second complementary MOS transistors, which transistors are connected in series together between one of the supply voltage references and a further voltage reference, have gate terminals connected together and to an input terminal of this buffer device, and have drain terminals connected together and to an output terminal of the buffer device. Advantageously, the first transistor is connected to the first supply voltage reference. Furthermore, the output buffer device comprises at least one additional drive MOS transistor of the same type as the first MOS transistor and placed between the second supply voltage reference and the output terminal of the buffer device.

Abstract: The present invention refers to a circuit disposal of a transistor shaped like a diode, in particular to a disposal able to reduce the threshold voltage of the transistor and equal to the difference of the threshold voltage of the used transistors in the circuit disposal. In an embodiment the circuit disposal comprises a first pMOS transistor (300) having a second pMOS transistor (301) shaped like a diode connected between the gate and the drain of the first transistor and a current generator (310) connected to the gates of the two transistors. Such a circuitry disposal it is also applicable to a nMOS transistor. From a general point of view this invention refers to a nMOS or pMOS transistor whose gate voltage is increased (for the nMOS transistors) or decreased (for the pMOS transistors) by using a circuit in series to the gate that provides an opportune delta of voltage.
