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.
