Abstract
A time of flight sensor is disclosed. In one example, it includes a pixel array with pixels arranged in rows and columns. A global control circuit disposed along a first side of the pixel array outputs a global control signal to the pixels. The global control circuit has a clock tree structure that includes buffer circuits and driving circuits. A rolling control circuit disposed along a second side of the pixel array outputs a rolling control signal to the pixels. A column circuit with analog-to-digital converters is coupled to the pixels.
