摘要： An image sensor having rows and columns of image pixels may include row control circuitry that controls voltages that are sent to each row of the image pixels. The row control circuitry may include booster circuitry that converts a positive power supply voltage (such as 2.8V) to voltages that are negative or otherwise less than the positive power supply voltage and/or greater than the positive power supply voltage. The booster circuitry may have a plurality of switches that control an input to an amplifier, thereby allowing the circuitry to produce any desired voltage in a given range. The booster circuitry output may be shared between multiple rows of the image pixels, and the produced boosted circuitry may be fed to any desired one or more of the rows of image pixels.
