Abstract
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.
