摘要： A method for driving a light-emitting semiconductor is provided. A supply voltage is converted into a secondary output voltage for supplying the light-emitting semiconductor with an output voltage. A level for the supply voltage at the beginning of a high current phase of the light-emitting semiconductor is sensed. A threshold voltage level for the supply voltage level is determined based on the sensed level. The high current phase with the light-emitting semiconductor is stated. The sensed level is continuously compared with the threshold voltage level, and an output current through the light-emitting semiconductor is controlled such that the sensed level does not drop below the threshold voltage level.

摘要： A digital driver circuit with one or more CMOS inverters intended as input stages, whereby for the MOS FETs of the inverters the channel width/length (W/L) ratio increases from stage to stage. The digital driver circuit includes an intermediate stage with two further CMOS inverters, connected between a supply voltage Vcc and ground. The driver circuit also includes an output stage having two MOS FETs with the drain terminals of both the MOS FETs of the output stage connected both to each other and to the output of the circuit, the W/L ratio of both MOS FETs exceeding that of the MOS FETs of the intermediate stage. The switch-over of the two MOS FETs of the output stage, occurring with changes of the digital input signal at the input of the circuit, is offset in time with respect to each other, thereby reducing current peaks.

摘要： Methods and systems for x-ray inspection of an object using pulses whose spectral composition varies during the course of each pulse. A temporal sequence of pulses of penetrating radiation is generated such that the spectral content of each pulse evolves with time. The pulses are formed into a beam that is scanned across the object and detected after traversing the object. The detector signal is processed to derive at least one material characteristic of the object, such as effective atomic number, on the basis of temporal evolution of the detector signal during the course each pulse of the sequence of pulses. The time intervals may be predetermined, or else adapted based on features of the detected signal.

摘要： Methods and systems for x-ray inspection of an object using pulses whose spectral composition varies during the course of each pulse. A temporal sequence of pulses of penetrating radiation is generated, each pulse characterized by an onset and by a spectral content that evolves with time subsequent to the onset. The pulses are formed into a beam that is scanned across the object. The penetrating radiation from the beam that has traversed the object is detected, generating a detector signal. The detector signal is processed to derive at least one material characteristic of the object, such as effective atomic number, on the basis of temporal evolution of the detector signal during the course each pulse of the sequence of pulses. The detector signal is separately acquired for multiple time intervals relative to the pulse onset, and processed to obtain values corresponding to multiple-energy analysis of the transmitted radiation. The time intervals may be predetermined, or else adapted based on features of the detected signal.

摘要： A method and apparatus are provided for determining the doping concentration profile of a specimen of semiconductor material. The apparatus includes a sensor assembly having a sensor tip which is mounted on an air bearing assembly. The air bearing assembly is suspended from a housing by a pair of bellows. In use, air is supplied to the air bearing assembly through the bellows causing the bellows to expand, lowering the sensor tip until the air bearing action stops the expansion. In other implementations of the invention, photocurrent or photovoltage are not used and the doping concentration profile is determined using the total capacitance, the capacitance of air, the DC bias voltage and the area of the electrode spaced from the specimen information.

摘要： A voltage regulator includes a two-stage feedback circuit for driving a controller formed by a transistor 10. The feedback circuit includes an error amplifier 30 and an output amplifier 20, a simple compensating circuit in the form of a resistor RSZ inserted between the inverting input 22 and the non-inverting input 24 of the output amplifier 20 resulting in a high phase reserve of the feedback circuit. The resistor RSZ limits the gain of the error amplifier 30 for small load currents by reducing its effective output impedance. This compensating circuit results in the two-stage feedback circuit being highly stable even when very low load currents are involved. This now makes it possible to achieve a very simple linear voltage regulator architecture totally integrated on a single chip. It is especially in battery-powered handhelds such as e.g. mobile phones or electronic organizers that this is important since these devices are often on standby with a low current consumption and activated for use only occasionally.
