摘要： A voltage regulator includes an input terminal adapted for being coupled to an input voltage and an output terminal adapted for being coupled to a load. The voltage regulator includes a first switch adapted for selectively coupling to the input terminal and to the output terminal, a current sensor for measuring an output current flowing towards the output terminal, a voltage sensor for measuring the output voltage from the output terminal, and a digital controller which drives the first switch. The controller closes the first switch when the error voltage is less than a first preset value of voltage and opens the first switch when the output current is greater than a first preset value of current.

The method includes detecting a reference value, comparing, instant by instant, the reference value with an output voltage value of the converter, and carrying out a switching from a transfer phase to an energy recirculation phase in correspondence with instants when the output voltage value reaches the reference value.

摘要： Photodetector device comprising a semiconductor substrate (1) of a first type of conductivity connected to a first electrode (2). Said substrate comprises an active area (4) made up of different semiconductor regions of a second type of conductivity (8, 9, 10) insulated from each other and connected to respective second electrodes (13, 14, 15) so that each of them can be connected separately from the others to an appropriate bias voltage. By regulating the bias voltages applied to these regions the function of optic diaphragm of the device can be controlled. The device works without needing any form of optical insulation between the different regions of the active area and always uses the same single output electrode for the signal in all the different situations of diaphragm adjustment.

摘要： A method for digital-to-analog conversion of a digital input code into a first output analog signal and a second output analog signal to be supplied to a first terminal and a second terminal, respectively, of an audio load, the conversion being performed by means of a DAC with N-level balanced output, the conversion method includes using N/2 positive generator elements supplying respective positive elementary contributions which are nominally equal to one another, and N/2 negative generator elements supplying respective negative elementary contributions which are nominally equal to one another and, in absolute value, equal to the positive elementary contributions; attributing the same progressive addresses to the positive generator elements and to the negative generator elements; defining a first index for the positive input codes and a second index for the negative input codes; and, in the presence of an input code at the input of the DAC, selecting between the first index and the second index, the index corresponding to the sign of the input code; activating a first set of positive generator elements and a second set of negative generator elements, the number of the positive generator elements activated and the number of the negative generator elements activated being equal to one another and proportional to the input code, and the addresses of the positive generator elements activated and of the negative generator elements activated being a function of the selected index; generating the first output analog signal by summing the positive elementary contributions supplied by the positive generator elements activated, and generating the second output analog signal by summing the negative elementary contributions supplied by the negative generator elements activated; and updating the selected index according to the input code.

摘要： The invention concerns an output circuit for extracting the avalanche pulse produced by an avalanche photodiode for single photon detection (Single Photon Avalanche Diode, SPAD), which makes possible to detect and measure with the best possible precision the time of arrival of an incident photon on the surface of said SPAD. The circuit is built with a coupling network, connected to a terminal of said SPAD biased at high voltage and a comparator. Said network is designed so that the differentiation time constant, introduced by said block, is less than the total duration of the avalanche current pulse, but longer than the risetime of said pulse (FIG. 5 and FIG. 8). The circuit object of the invention has the virtue of being usable in all the circuit configurations for avalanche quenching in SPADs described in the technical and scientific literature.
