<p>A circuit for obtaining an output from a CCD type signal processing circuit should operate satisfactorily in a high frequency band covering, for instance, video signals. For this purpose, the floating gate electrode (7) of the CCD is connected to a first potential level (VGG) through first and second capacitors (Cc, Co). The connecting point of the floating gate electrode (7) in the series circuit is connected to a second potential level (VT) through a first control switch (Q2) which is driven by a reset clock pulse (OR); and the connecting point of the first and second capacitors is connected to a third potential level (Vo) through a second control switch (Q1) which is driven by a reset clock pulse (OR), so that the output is provided at the connecting point of the capacitors.</p> |
