ABSTRACT:
The invention relates to a charge-coupled device with an adjustable charge transport route having at least two ccd segments, which can be connected in series with each other by means of a switchable connection. This connection includes an output diode for the first segment, an input diode for the first segment, an input diode for the second segment and a switch, for example a MOS transistor, which is connected to the output diode and/or the input diode. The input diode and the output diode may be in the form of individual zones or in the form of individual zones or in the form of a common zone. The invention, which offers the advantage that the transport time through the connection independent of the length of the form of the connection, can be used, for example, in programmable filters, (de)multiplexers, (de)scramblers and the like.
