Abstract: A charge transfer device having a charge transfer channel in a semiconductor substrate. The charge transfer channel is formed by overlap of the possible electrostatic effect of the gates with the conduction layer. A clock generator has a clock frequency of more than 100 MHz which applies changes in potential at the clock frequency to the gates, for transporting charge carriers at the clock frequency from adjacent regions of the overlap between adjacent gates and the conduction layer. The charge transfer channel has an influx region which, in the flow direction, is arranged at a lateral outer boundary of the charge transfer channel and which at least partly extends over the regions of exactly two adjacent gates of the charge transfer channel in order to supply charge carriers to the charge transfer channel from a region outside the charge transfer channel that adjoins the influx region from a second charge transfer channel.

Abstract: A charge transfer device having a charge transfer channel in a semiconductor substrate. A doped conduction layer is provided for movably accepting the charge carriers, and a sequence of at least two electrically isolated gates which adjacently succeed one another for transferring the charge carriers in the conduction layer in a flow direction is provided. The charge transfer channel is formed by overlap of the possible electrostatic effect of the gates with the conduction layer. A clock generator has a clock frequency of more than 100 MHz which applies changes in potential at the clock frequency to the gates, for transporting charge carriers at the clock frequency from adjacent regions of the overlap between adjacent gates and the conduction layer. The charge transfer channel in the region of one gate has a region of a constriction in which the cross-section in the flow direction decreases, and has a region with a constant or widened cross-section.

Abstract: A method for reading a demodulation pixel of a distance sensor for determining a distance, in particular for determining the difference between two charge quantities independently of the total magnitude of the charge quantities, and also a distance sensor are proposed. For faster signal processing, provision is made for applying a variable control voltage to the transfer gates for influencing the potential wall, and lowering the respective potential walls of the corresponding transfer gates, before and/or until from the storage gates in each case charge carriers can surmount the respective potential wall of the corresponding transfer gate and pass to the assigned floating diffusion.
