Correlated time-of-flight sensor

A time-of-flight (TOF) sensor, comprising:

• a light source structured to emit light;
• a plurality of avalanche photodiodes structured to receive the light;
• a plurality of pulse generators, wherein individual pulse generators in the plurality of pulse generators are coupled to individual avalanche photodiodes in the plurality of avalanche photodiodes;
• and
• control circuitry coupled to the light source, the plurality of avalanche photodiodes, and the plurality of pulse generators, wherein the control circuitry includes logic that when executed by the control circuitry causes the time-of-flight sensor to perform operations, including:
• emitting the light from the light source;
• receiving the light reflected from an object with the plurality of avalanche photodiodes;
• in response to receiving the light with the plurality of avalanche photodiodes, outputting a plurality of pulses from the individual pulse generators corresponding to the individual avalanche photodiodes that received the light;
• and
• in response to outputting the plurality of pulses, outputting a timing signal when the plurality of pulses overlap temporally.
