    摘要： A circuit includes a rectifier, e.g., including four diodes; a semiconductor switch; a coil that is chargeable, is dischargeable, and has (a) a first terminal connected to a first output terminal of the rectifier and (b) a second terminal connected via the semiconductor switch to a second output terminal of the rectifier; a first resistor via which a control terminal of the semiconductor switch is connected to the first output terminal of the rectifier; a second resistor connected between the second output terminal of the rectifier and the control terminal of the semiconductor switch; and a discharge unit connected between the second terminal of the coil and the control terminal of the semiconductor switch. The charging and discharging is implemented by, respectively, connecting both of, and disconnecting one or both of, first and second input terminals of the rectifier to/from the voltage source.

    摘要： A method for processing input variables using a processing device having at least a first transistor, for example a field-effect transistor. The method includes: providing the first transistor and a first memristive circuit device which characterizes a first input variable associated with the first transistor, wherein a charging current of a capacitor associated with a control electrode of the first transistor can be influenced by means of the first memristive element; applying to the control electrode of the first transistor a first control signal which characterizes a second input variable associated with the first transistor and which has at least periodically a non-constant amplitude; ascertaining a first output variable on the basis of a first variable characterizing a time curve of a current through a load path of the first transistor.

    摘要： An image sensor element for outputting an image signal. The image sensor element initially includes a first photoelement, the first photoelement being situated on a spatial area of a pixel on a semiconductor substrate. The image sensor element also includes a second photoelement that is doped and/or provided with a color filter in such a way that a spectral sensitivity of the first photoelement differs from a spectral sensitivity of the second photoelement. Lastly, the image sensor element includes an evaluation electronics system that is situated in the area of the pixel on the semiconductor substrate, the evaluation electronics system being situated in the area of the pixel in which the first photoelement is also implemented. The evaluation electronics system is designed to process a photoelement signal of the first photoelement and a photoelement signal of the second photoelement to form the image signal.
