  • Circuit for generating direct timing histogram data in response to photon detection
    Patent number: 9502458
    Abstract: A sensor pixel detects a photon and outputs a first voltage proportional to a time of arrival of the detected photon. This voltage is converted to a multi-bit digital signal in the format of a thermometer code. A number of counter circuits, one counter circuit per bit of the multi-bit digital signal, are provided to accumulate the thermometer coded outputs. Each counter is configured to increment in response to an active logic state of the corresponding bit of the multi-bit digital signal. Accumulated count values in the counter circuits provide a timing histogram with respect to photon detection.
