    摘要： A voltage-regulator device includes an error-amplifier stage configured to receive a first reference voltage and a feedback voltage, an output amplifier stage coupled to the error-amplifier stage and configured to generate an output voltage related to the first reference voltage by an amplification factor, and a feedback stage configured to generate the feedback voltage. A compensation stage is configured to implement a second feedback loop, and cause, in response to a variation of the output voltage, a corresponding variation of a first biasing voltage for the output amplifier stage. The compensation stage includes a coupling-capacitor element coupled between the output amplifier stage and a first internal node, and a driving module coupled between the first internal node, and the output amplifier stage and configured to generate a compensation voltage for driving the output amplifier stage.

    摘要： A digital-to-analog converter (DAC) may include a conversion block providing a first analog value. The DAC may also include an amplification block for receiving the first analog value and providing a second analog value amplified by an amplification factor. The amplification block may include a first input terminal for receiving the first analog value, a second input terminal, and an output terminal for providing the second analog value. The amplification block may also include a first capacitive element and a second capacitive element. The first and second capacitive elements may determine the amplification factor. The amplification block may further include a control unit for recovering a charge at a first terminal of the second capacitive element, and based thereon, the second analog value.

    摘要： An electronic switch may include transfer transistor having a first conduction terminal for receiving an input signal, a second conduction terminal, and a control terminal. The transfer transistor may enable/disable a transfer of the input signal from the first conduction terminal to the second conduction terminal according to a control signal. The control signal may take a first value and a second value different from the first value, a difference between the first value and the second value defining, in absolute value, an operative value of the control signal. The electronic switch may further comprise a driving circuit for receiving the input signal and the control signal, and for providing a driving signal equal to the sum between the input signal and the operative value of the control signal to the control terminal of the transfer transistor.

    摘要： A driving stage for a phase change non-volatile memory device may include an output driving unit, which supplies an output driving current during programming of a memory cell, a driving-control unit, which receives an input current and generates a first control signal for controlling supply of the output driving current in such a way that a value thereof has a desired relation with the input current, and a level-shifter element, which carries out a level shift of a voltage of the first control signal for supplying to the output driving unit a second control signal, having a voltage value that is increased with respect to, and is a function of, the first control signal. A calibration unit may carry out an operation of updating of the value of a shift voltage across the level-shifter element, as the value of the input current varies.
