SOLID-STATE IMAGING APPARATUS, DRIVING METHOD THEREFOR, AND CAMERA |
摘要 |
In a CCD imaging device in which sensor sections have the vertical overflow drain (OFD) structure, a substrate bias control signal is applied to the base of a bipolar transistor via a resistor to turn on the transistor at least during a signal charge readout period. As a result, the base potential of a bipolar transistor that constitutes a clamping circuit is lowered, whereby a substrate bias that is output from a substrate bias generation circuit is lowered. Thus, the potential of an overflow barrier in the sensor sections is reduced.
