    Abstract: An imaging system may include imaging pixels. Each imaging pixel may include a reset transistor and a dummy transistor coupled to a floating diffusion storage node. When reset signals control are deasserted, capacitive coupling between the gate terminal of the reset transistor and the source-drain terminals of the reset transistor may lead to reset charge injection. The dummy transistor may have both of its source-drain terminals shorted together and shorted to the floating diffusion region. Dummy control signals, which may be provided by separate dummy control lines or may be provided using row-select signals, may be asserted on the dummy transistors at approximately the same time that the reset signals are deasserted. With arrangements of this type, the dummy control signals may inject an approximately equal and opposite charge onto the floating diffusion region, thereby reducing the reset charge injection caused by deasserting the reset control signals.

    Abstract: An object is to provide a photosensor utilizing an oxide semiconductor in which a refreshing operation is unnecessary, a semiconductor device provided with the photosensor, and a light measurement method utilizing the photosensor. It is found that a constant gate current can be obtained by applying a gate voltage in a pulsed manner to a transistor including a channel formed using an oxide semiconductor, and this is applied to a photosensor. Since a refreshing operation of the photosensor is unnecessary, it is possible to measure the illuminance of light with small power consumption through a high-speed and easy measurement procedure. A transistor utilizing an oxide semiconductor having a relatively high mobility, a small S value, and a small off-state current can form a photosensor; therefore, a multifunction semiconductor device can be obtained through a small number of steps.
