Solid-state imaging device and method for driving same

2013 
Provided are a solid-state imaging device and a method for driving same whereby the amount of time required for noise canceling can be substantially reduced. The solid-state imaging device is provided with a signal read-out circuit and a negative-feedback circuit. The signal read-out circuit contains the following: a charge storage section that is electrically connected to a photoelectric conversion section; and a reset transistor, either the source or drain of which is electrically connected to the charge storage section. The negative-feedback circuit provides the output of the signal read-out circuit to either the source or the drain (whichever is not electrically connected to the charge storage section) of the reset transistor as negative feedback. A reset operation that dumps charge stored in the charge storage section comprises a first period and a second period after said first period. The negative-feedback circuit is in an off state during the first period and an on state during the second period. During the first period, the reset transistor transitions from an off state to an on state and then back to the off state. During the second period, a reset-transistor control voltage that gradually transitions the reset transistor to the on state is applied.
