摘要： An input current (I in ) is transformed into an output integrated voltage (V out_int ) using a parallel connection of an operational transconductance amplifier and an integration capacitor. The output integrated voltage is reduced by repeatedly discharging the integration capacitor through a feedback loop via a digital-to-analog converter generating feedback pulses, a feedback clock period (T clk_DAC ) defining time intervals between successive rising edges of the feedback pulses.Sampling is performed during an extended feedback clock period (T*) after a lapse of a plurality of feedback clock periods (T clk_DAC ).

摘要： A rotary sensor arrangement is configured to be used with a rotatable magnetic source and comprises a first and a second pair of magnetic field sensors, each pair arranged symmetrically with respect to rotation axes and providing respective sensor values. An evaluation unit determines a first sum value corresponding to a sum of the sensor values of the first pair, and a second sum value corresponding to a sum of the sensor values of the second pair. The evaluation unit further determines a difference value (F) corresponding to a difference between the first and the second sum value and compares the difference value (F) or a value derived thereof to a threshold value. Based on the comparison result, it is determined whether a failure status of the sensor arrangement is present.

摘要： A lighting control system (LCS) for generating supply currents for at least two LED channels (CH1, CH2, CHn) comprises at least two controlled current sources for generating a supply current for a corresponding LED channel based on a corresponding control signal. The system further comprises at least two signal combiners for generating the corresponding control signals based on a synchronization signal (VSYNC) that comprises periodic starting pulses and on a combination of a magnitude dimming signal and a pulse dimming signal corresponding to one of the LED channels.
