Abstract
An analog signal processing apparatus of series write-in and parallel read-out type includes a charge transfer device with a plurality of stages and for transferring sampled analog signal charge packets in response to transfer pulses applied. After stoppage of transfer pulses supply, a signal charge packet is shifted to a storage region provided adjacent to a signal charge storage site at each stage. The signal charge packet is kept in the storage region until an analog input signal is rewritten into the device. A signal charge read-out device is coupled with the storage region. The amount of signal charge stored in the storage region increases with time during the charge storage period of time due to generation of dark current charge. Means for removing dark current charge is provided.
