摘要： A time delay logic comprises a first stage with an inverter, a capacitor connected to the input terminal of the inverter, a constant current generator and an electronic switch controlled by an input pulse. The capacitor begins to charge at a predetermined edge of the input pulse and brings the input terminal of the inverter from a first voltage (ground) to the switching threshold voltage of the inverter, so that on the output terminal of the inverter there is obtained a pulse having an edge that, as referred to the predetermined edge of the input pulse, has a delay time that depends on the inverter threshold. The circuit comprises a second stage, coupled with the first, that is a dual circuit of the circuit of the first stage and has an inverter equal to the one of the first stage.

摘要： A system includes analog supply circuitry providing first and second analog potentials. A switch module assumes first or second states to enable and inhibit transfer of an analog electrical signal from a source module to a user module based upon a driving electrical signal. A driving device drives, based upon the driving electrical signal, a control terminal of the switch module, allowing the switch module to assume the first or second state. The driving device allows the switch module to make a first driving transition from the first state to the second state, and a second driving transition from the second state to the first state. The driving device alternately connects the control terminal to a first reference potential, during the first state, and to a second reference potential, during the second state. The driving device connects the control terminal of the switch module to a third reference potential electrically distinct from the first and the second analog potentials, during each of the time intervals associated to the first or second driving transitions of the switch module.

摘要： An analog/digital converter for converting an analog signal to a digital output code includes a local digital analog converter including a segmented array. The segmented array includes upper and lower segments of conversion elements selectively operable by respective digital command codes for respectively varying, according to binary weighted contributions, the voltages of first and second common nodes and the voltage of a second common node. A logic unit generates the digital command codes for controlling the local digital/analog converter according to a successive approximation technique for producing the digital output code. The converter includes a redistributor for modifying the command codes for redistributing the modified command codes between the lower segment and the upper segment, while making use of at least one auxiliary conversion element provided in the upper segment.
