Local pixel driver circuitry

An image sensor may include an array of image sensor pixels. Each image sensor pixel in the array may be a global shutter pixel that includes first transistors and second transistors that are substantially larger than the first transistors. The second transistors may receive row control signals from peripheral row drivers formed at the edge of the array. Each pixel may further include local driver circuits interposed between the peripheral row drivers and the second transistors. Each local driver circuit may include a pull-down transistor for driving a row control signal low and a pull-up transistor for driving the row control signal high. Each local driver may optionally be shared among two or more adjacent pixels in a given row. The local drivers help reduce the total capacitive loading at the output of the peripheral row drivers and can therefore help improve row driver performance and minimize integration time.
