    Abstract: A reading circuit for a charge-retention circuit stage is provided with a storage capacitor coupled between a first biasing terminal and a floating node, and a discharge element coupled between the floating node and a reference terminal. The reading circuit further has an operational amplifier having a first input terminal that is coupled to the floating node and receives a reading voltage, a second input terminal receives a reference voltage, and an output terminal on which it supplies an output voltage, the value of which is a function of the comparison between the reading voltage and the reference voltage and indicative of a residual charge in the storage capacitor. A shifting stage shifts the value of the reading voltage of the floating node, before the comparison is made between the reading voltage and the reference voltage for supplying the output voltage.

    Abstract: An electronic system is configured to generate a sequential logic signal. The electronic system includes a first ring oscillator including a first plurality of cascaded inverter stages. A combinational logic circuit is configured to generate the sequential logic signal by combining signals at the output terminals of at least two of the inverter stages of the first ring oscillator. The electronic system further includes a second ring oscillator including a second plurality of cascaded inverter stages. A bias current source is configured to supply the inverter stages of the second ring oscillator with a bias current, and a first voltage is generated at the inverter stages of the second ring oscillator. A voltage follower is configured to supply the inverter stages of the first ring oscillator with a second voltage corresponding to the first voltage generated at the inverter stages of the second ring oscillator.

    Abstract: 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.
