The control circuitry is coupled to synchronously send a sync signal. The time of flight pixel array includes a plurality of time of flight pixel cells. Each one of the time of flight pixel cells includes a photosensor and a delay circuit. The photosensor is configured to generate an image signal in response to receiving photons from a light pulse reflected from an object. The delay circuit is coupled to generate a delayed sync signal in response to the sync signal. The delay circuit includes a delay transistor. The time of flight pixel array includes a transistor gradient where a transistor gate length of the delay transistor varies so that each of the time of flight pixel cells receive their respective delayed sync signal at a same time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time of flight imaging with improved initiation signaling","description":"A time of flight sensor includes control circuitry and a time of flight pixel array.
