Abstract: A laser diode driver circuit includes a first pair of contacts and connectors coupled to an anode of the laser diode. An inductance of each of the first pair of contacts and connectors is the same. A second pair of contacts and connectors are coupled to a cathode of the laser diode. An inductance of each of the second pair of contacts and connectors is the same. The laser diode driver circuit also includes current driving circuitry.

Abstract: An embodiment method of operating an imaging device including a sensor array including a plurality of pixels, includes: capturing a first low-spatial resolution frame using a subset of the plurality of pixels of the sensor array; generating, using a processor coupled to the sensor array, a first depth map using raw pixel values of the first low-spatial resolution frame; capturing a second low-spatial resolution frame using the subset of the plurality of pixels of the sensor array; generating, using the processor, a second depth map using raw pixel values of the second low-spatial resolution frame; and determining whether an object has moved in a field of view of the imaging device based on a comparison of the first depth map to the second depth map.

Abstract: A distance from an apparatus to at least one object is determined by generating a first signal and generating light modulated by the first signal to be emitted from the apparatus. Light reflected by the at least one object is detected using a Time-of-flight detector array, wherein each array element of the Time-of-flight detector array generates an output signal from a series of photon counts over a number of consecutive non-overlapping time periods. The output signals are compared to the first signal to determine at least one signal phase difference. From this at least one signal phase difference a distance from the apparatus to the at least one object is determined.

Abstract: In some embodiments, a ToF sensor includes an illumination source module, a transmitter lens module, a receiver lens module, and an integrated circuit that includes a ToF imaging array. The ToF imaging array includes a plurality of SPADs and a plurality of ToF channels coupled to the plurality of SPADs. In a first mode, the ToF imaging array is configured to select a first group of SPADs corresponding to a first FoV. In a second mode, the ToF imaging array is configured to select a second group of SPADs corresponding to a second FoV different than the first FoV.

Abstract: The present disclosure includes a method that includes generating a decoded output signal that corresponds to reflected light received by a plurality of single photon avalanche diodes (SPAD) by removing ambient light from a plurality of SPAD array output signals. The removing of ambient light including synchronizing the plurality of SPAD array output signals by using a plurality of parallel time to digital converters, each time to digital converter outputting a synchronized SPAD array output signal, determining a plurality of flexible thresholds for each one of the synchronized SPAD array output signals, comparing current data on the synchronized SPAD array output signals with the respective ones of the flexible threshold in a filter, and outputting the first output signal.

Abstract: SPADs detect photons of a return light pulse and output corresponding pulse signals. First and second counters, when enabled in response to phase measurement value, are configured to count the pulse signals. The phase measurement value is set for a subsequent iteration of the return light pulse in response to processing of first and second count values of the first and second counters, respectively, for a current iteration. If the first count value exceeds the second count value by more than a difference threshold limit, the phase measurement value is decremented for the subsequent iteration. Otherwise, the phase measurement value is incremented for the subsequent iteration. If the difference threshold limit is not satisfied, the phase measurement value may be maintained for the subsequent iteration, but one of the counters is preloaded for the subsequent iteration with a value equal to a magnitude of the difference between the count values.

Abstract: A time to digital converter includes a sample module operable to sample an input signal at multiple different instances of time. A transition detection module, formed of comparison elements, processes the sampled input signal at successive time instances so as to detect transitions in the input signal in terms of time. An output module generates detected transitions in the input signal on multiple parallel outputs.
