IMAGING DEVICE AND PROTECTION DEVICE OF SOLID-STATE IMAGING DEVICE

摘要

Protection of a solid-state imaging device is disclosed. One example of a protection unit includes a capacitor connected between an output terminal of a shutter drive pulse of a pulse drive unit and a substrate voltage terminal of a solid-state imaging device, a diode connected between a predetermined potential point and the substrate voltage terminal, and a clamp circuit configured from a resistor element connected between the substrate voltage terminal and a reference potential point. An anode end of the diode is connected to the predetermined potential point to which a potential corresponding to a rated voltage of the substrate voltage terminal is applied.
