Abstract
Regenerator circuit for CCD elements in which charge representing information is transferred from a first CCD element to a second CCD element. The circuit includes a first MOS capacitance and a second capacitance connected in series with the first capacitance, the point at which the two capacitances are connected with one another being connected to the input of said second CCD. The output of the first CCD includes an output stage having an output diffusion zone. A transistor is connected between a terminal to which a potential .phi..sub.v can be connected and the point between said first and second capacitances. This transistor has a gate electrode which is connected by a line to the output diffusion zone of the first CCD.
