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： 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.
