    Abstract: A LiDAR readout circuit is described. The readout circuit comprises an SiPM sensor for detecting photons and generating an SIPM analog output signal. A plurality of comparators are provided each having an associated threshold value and being configured to compare the SiPM analog output signal with their associated threshold value and generate a comparison signal. A time to digital converter is configured to receive the comparison signals from the plurality of comparators.

    Abstract: An apparatus for photon counting is disclosed that comprises a sensor element (5) comprising a photon detector (8) and a capacitance (2) for applying a potential difference across the detector (8). The apparatus also comprises switching circuitry (6) for connecting the sensor element (5) operatively to a voltage source (4) during a refresh period to charge the capacitance (2) to achieve a predetermined potential difference across the detector (8) above a threshold value, and for substantially isolating the sensor element (5) from the voltage source (4) during a sensing period in which the charged capacitance (2) maintains a potential difference across the detector (8) above the threshold value and in which the detection of a photon by the detector (8) causes at least some of the charge on the capacitance (2) to discharge through the detector (8). The apparatus also comprises control circuitry (12) for controlling the switching circuitry (6) to initiate refresh and sensing periods in alternating sequence. In one aspect, the control circuitry (12) is adapted to control the switching circuitry (6) to initiate successive refresh periods at predetermined intervals.

    Abstract: In one form, a process of manufacturing an avalanche photodiode includes forming an insulating layer over an active region of a semiconductor substrate. A shallow terminal of the avalanche photodiode is defined using a first patterned mask. A first dopant is implanted through the first patterned mask and the insulating layer to form the shallow terminal. The first patterned mask is removed. A deep terminal of the avalanche photodiode is defined using second patterned mask. A second dopant is implanted through the second patterned mask and insulating layer to form the deep terminal of the avalanche photodiode. A respective terminal of at least one of the shallow terminal and the deep terminal is defined using a respective patterned mask that forms at least two regions that are spatially separated from each other with no implanted structure located in a space therebetween.
