Abstract: A controller for controlling an amplification gain of an amplifier for amplifying a high dynamic range signal for an analog to digital converter comprises an input interface adapted to receive a representation of the high dynamic range signal and a signal compressor adapted to provide a low amplitude representation of the high dynamic range signal, the low amplitude representation having a lower signal amplitude than the high dynamic range signal. A comparator is adapted to compare the signal amplitude of the low amplitude representation with a predetermined threshold and an output interface is adapted to provide a control signal to the amplifier, the control signal being adapted to control the amplification gain of the amplifier such that the amplification gain is lowered when the signal amplitude of the low amplitude representation exceeds the predetermined threshold.

Abstract: An apparatus for generating a sensor signal indicating information on a capacitance of a variable capacitor including a variable capacitance includes a sensor unit and a compensation unit. The sensor unit is configured to generate a sensor signal indicating information on a varying current flowing through a connection between the sensor unit and the variable capacitor caused by a variation of the capacitance of the variable capacitor while the variable capacitor is biased by a predefined bias voltage. Further, the compensation unit is configured to influence the sensor signal or to provide a compensation signal capable of influencing the sensor signal so that the sensor signal includes less nonlinear signal portions than a sensor signal without the influence of the compensation unit or the compensation signal.

Abstract: A nonlinear converter, such as a DC-DC converter, includes a nonlinear controller configured to receive an output voltage and a current, and configured to generate a PWM signal. The PWM signal is generated based on setting the converter to a first phase associated with both buck and boost modes when a clock signal is asserted, and selecting a second phase associated with the buck mode of the converter, if a sliding function signal achieves a first predetermined relationship with respect to a buck threshold before a next clock signal is asserted, or selecting a third phase associated with the boost mode of the converter, if the sliding function signal achieves a second predetermined relationship with respect to a boost threshold before a next clock signal is asserted. The nonlinear converter may include a power stage configured to provide the output voltage and a coil current to the nonlinear controller.

Abstract: The method is used for limiting the power of a transmission-end signal (xn) compiled from a plurality of differently spread-coded signals. In this context, it is assumed that the quantity of spread codes used for the differently spread-coded signals is known as code engagement information (Cch,SF,k; 80). First, correction spread codes are selected by virtue of the engagement information (Cch,SF,k; 80) being evaluated. On the basis of the selected correction codes, a spread-coded correction signal (y?n) is formed which is overlaid with the compiled signal (xn).
