The present invention relates to a method and an electronic circuit for processing at least two at least partially correlated output signal streams of a mixer, the mixer having at least two signal inputs and at least two electric signal outputs. In order to provide a method and a device or an electronic circuit which enables the correlated signal portions of the output signals of a mixer to be separated from the uncorrelated signal portions undelayed, it is proposed according to the invention that the difference of the output signal streams of the mixer is formed pairwise directly and during the readout of the signal streams and that the circuit has an apparatus for the instantaneous formation of the difference between the signal streams of two mixer outputs in each case.

Signal-processing electronics

The present invention relates to a photonic mixer device with a photosensitive layer, at least two modulation gates () and at least two readout electrodes () connected to the photosensitive layer, the modulation gates () being able to be connected to a modulation device which raises and lowers the potential of the modulation gates relative to one another and relative to the preferably constant potential of the readout electrodes corresponding to a desired modulation function. In order to further develop the known photonic mixer device such that it shows an increased charge conversion efficiency and reduced dark currents, it is proposed according to the invention that the readout electrodes () in each case have at least two discrete electrode sections (A-E,A-E) arranged at a distance alongside each other.
