Abstract
A time-of-flight (TOF) sensing system may include an illumination module and a sensor module. The sensor module may include an array of sensor pixels, pixel-level readout circuitry, and column-level readout circuitry coupled to the pixel-level readout circuitry via corresponding column lines. Pixel-level readout circuitry may be provided on a per-pixel basis (e.g., dedicated or unshared per-pixel readout circuitry may be provided for each pixel). Pixel-level readout circuitry may include one or more correlated double sampling stages and a storage stage. The storage stage may include a set of capacitors each configured to store different phase data generated by a corresponding pixel for a TOF sensing operation.
