An oscillator circuit (


In one embodiment an Inductive buck-boost-converter has an input (In) to which an input voltage (Vin) is supplied, an output (Out) at which an output voltage (Vout) is provided as a function of the input voltage (Vin), an inductor (L) having a first and a second terminal (Lx


A sensor arrangement comprises at least a first, a second, and a third light sensor. A three-dimensional framework comprises at least a first, a second, and a third connection means which are connected to the at least first, second, and third light sensor, respectively. The first, the second, and the third connection means are configured to align the at least first, second, and third light sensor along a first, second, and third face of a polyhedron-like volume, respectively, such that the sensor arrangement encloses the polyhedron-like volume. The invention also relates to a method for operating the sensor arrangement.


A capacitance-to-digital converter (


An optical sensor circuit comprises an optical sensor (DET) designed to provide a sensor signal indicative of a color of light incident on the optical sensor (DET), a clock designed to provide a clocked control signal comprising consecutive high and low states, and a controller unit (CU) connected to the optical sensor (DET) and comprising the clock. The controller unit (CU) is designed to process the sensor signal as a color signal (CTS) in a first mode if the clocked control signal is in a high state, wherein the color signal (CTS) is indicative of a color of light emitted by a light emitting device (LED) to be connected at a control terminal (OUT). The controller unit (CU is further designed to process the sensor signal as an ambient color light signal (aCTS) in a second mode if the clocked control signal is in a low state, wherein the ambient color light signal (aCTS) is indicative of a color of ambient light. The controller unit (CU) is also designed to generate a driving signal (PWM) to drive the light emitting device (LED), wherein the driving signal (PWM) depends on the color and ambient color light signal (CTS, aCTS).
