A pixel arrangement includes a photodiode, a reset transistor configured to be controlled by a reset signal and coupled to a reset input voltage, a transfer gate transistor configured to transfer charge from the photodiode to a node, wherein the transfer gate transistor is controlled by a transfer gate voltage, and a source follower transistor controlled by the voltage on the node and coupled to a source follower voltage. A capacitor is coupled between the node and an input voltage. During a read operation the input voltage is increased to boost the voltage at the node. The increased input voltage may, for example, be one the reset input voltage, said source follower voltage, said transfer gate voltage and a boosting voltage.

Pixel circuit

An IC image sensor device may include image sensing IC pixels arranged in an array, and pixel line pairs coupled to the image sensing IC pixels. The IC image sensor device may include circuitry coupled to the pixel line pairs and configured to operate the array in a global shutter mode. Each pair of the pixel line pairs may include a pair of spaced electrical conductors having a twist.

IC image sensor device with twisted pixel lines and related methods

An image sensor including an array of pixels, each having: a storage node coupled to a capacitive sense node by a transfer transistor; and a connection transistor coupling the pixel sense node to an intermediate node of the pixel, wherein each pixel has its intermediate node coupled to a node of application of a reset voltage by a reset transistor, and different pixels have their respective intermediate nodes interconnected by a conductive connection track.
