摘要： A method for producing a self-supporting electron-optical transparent structure that includes multi-layer strips and recesses located between the multi-layer strips. The method includes applying a first layer to a second layer, presetting a pattern by exposing or irradiating the first layer and etching the pattern out of the first layer so that partial areas of the second layer are uncovered. The method further includes galvanically applying layers to the uncovered partial areas of the second layer so that multi-layer strips are formed thereon and an electron-optical transparent structure is formed and removing the electron-optical transparent structure off the second layer.

摘要： A recording medium with a multicolor high resolution pattern created by layer packs. Pattern-forming layers of the layer packs are successively applied by photolithographic means in a sequence corresponding to a color of the high resolution pattern. The pattern-forming layers of the layer packs are separate from one another on the substrate of the recording medium.The process for producing the recording medium includes applying a photoresist layer to a substrate and developing the photoresist. Pattern-forming layers are successively applied over the whole surface of the substrate in a sequence corresponding to a color. The remaining photoresist and the layers overlying it are removed to leave a sequence of pattern-forming layers on the substrate separate from any adjacent pattern-forming layers.

摘要： A self-oscillating DC-DC buck converter with zero hysteresis is described. The converter comprises a comparator with a supply input, a non-inverting input to which a reference voltage is applied, an inverting input to which a feedback signal is applied, and an output to which a filter network is connected. The feedback signal is derived from the filter network and the output voltage of the converter is determined by the reference voltage. Connecting a filter network with an inductor and a capacitor to the output of the comparator and deriving the feedback signal from the filter network, results in an output of the comparator which is a DC output with a superimposed ripple. The level of the DC output is controlled by the reference voltage applied to the non-inverting input of the comparator, and the inductor current develops the ripple in the equivalent series resistance of the load circuit connected to the comparator output. The ripple can be regarded as the ramp signal in a conventional DC-DC converter. Accordingly, the output voltage is regulated to follow the reference voltage, and the proposed topology is equivalent to a DC-DC buck converter.

摘要： A buck-boost DC/DC converter includes an inductor and a power stage having a set of switches selectively connecting the inductor between a voltage input, a voltage output and a reference level in accordance with buck or boost mode. The converter has a switch control providing control signals to the set of switches in the power stage. A comparator provides to the switch control a first pulse width modulation signal in buck mode and a second pulse width modulation signal in boost mode. A ramp generator provides to the comparator a first ramp signal for buck mode and a second ramp signal for boost mode. An overlap control provides a ramp shift signal to the ramp generator in response to a detection signal that indicates activity of the switches in the power stage. The ramp shift signal adjusts the first and second ramp signals relative to each other so as to minimize any gap and any overlap between the first and second ramp signals. Whenever actuation of all switches in the power stage within the same clock period is detected, the ramp signals are adjusted in a way to reduce the overlap between the ramp signals. Conversely, when no switch activity is detected in a clock period, the ramp signals are adjusted in a waye to increase the overlap between the ramp signals. As a result, when the input voltage is close to the output voltage, the converter alternatively operates in buck mode or in boost mode, avoiding a buck-boost mode.

摘要： A power switching circuit in CMOS technology has a power MOS transistor and a driver stage. The power MOS transistor is operated at a higher supply voltage in excess of its maximum allowable gate-source voltage; and the driver stage of the level shifter is operated at a lower supply voltage substantially lower than the supply voltage for the power MOS transistor. The driver stage includes a pair of driver MOS transistors coupled in series between a higher supply voltage rail and a reference potential rail, and at an interconnection node coupled to the gate of the power MOS transistor. The gates of the driver MOS transistors are AC-coupled to drive signals of mutually opposite phase; and the gates of the driver MOS transistors are each connected to the higher voltage supply rail through a respective parallel connection of a first resistor and a second resistor connected in series with a non-linear component. The resistance value of the second resistor is substantially smaller than the resistance value of the first resistor.

摘要： A DC-DC boost converter comprises a charge pump selectively operating in a voltage doubler or in a voltage tripler mode. A switching arrangement connects the charge pump to an input voltage terminal in a charge phase and to an output voltage terminal in a discharge phase. A controllable current source is connected in series with the charge pump in the discharge phase and an error amplifier has a first input connected to a reference voltage, a second input connected to the output voltage terminal and an output connected to a control input of the controllable current source. The converter further comprises a mode changeover circuit with a first comparator having a first input connected to the output of the error amplifier and a second input connected to a first threshold voltage source. A second comparator has a first input connected to the output of the error amplifier and a second input connected to a second threshold voltage source. A flip-flop has its set input connected to the output of the first comparator, its reset input connected to the output of the second comparator. The flip-flop has its output connected to the switch arrangement to switch the charge pump from doubler mode to tripler mode when the voltage at the output of the error amplifier exceeds the second threshold voltage and back to doubler mode when the output voltage at the error amplifier drops below the first threshold voltage.
