摘要： An input structure of CCD comprises a primary register having an input gate and a source region and an automatic biasing system which generates a feedback signal to be fed back to input of the primary register. The output of the automatic biasing system is connected to one of the input gate and the source of the primary register for supplying the feedback signal thereto for adjusting input bias level of the primary register. The other one of the input gate and the source is connected to an information signal input terminal to receive therefrom an information signal to be transferred therethrough.

摘要： An output stage of a solid-state image pick-up device, such as a CCD solid-state image pick-up device is accurately operable even under a lower source source voltage is easy to design and does not require substantial precision in production. The improved output stage construction of a solid-state image pick-up device, according to the present invention, has a buffer circuit, connected to at least one of a input side or a output side of an output stage circuit component, such as an amplifier circuit, and a low-pass filter source source. The buffer circuit is so designed as to have a constant DC level and a gain about 1.
