    Abstract: Some aspects of the present disclosure provide system and method of operation of a driving circuit for a light emitting element in a Time-of-Flight (ToF) camera. A DC-DC converter is configured to emit a constant current, and is coupled in parallel to a first modulation switch configured to connect the driving circuit to ground. The first modulation switch is further configured to alternate connections between the current source and ground at a frequency in a desired range of operation to produce an AC current. In some embodiments, an RC circuit element is coupled to an output electrode of the light emitting element and configured to apply a reverse bias to decrease turn-off time of the light emitting element. In some embodiments, a second modulation switch is coupled to the output electrode and configured to apply the reverse bias across the light emitting element. Other systems and methods are also disclosed.

    Abstract: Time-of-flight (TOF) systems and techniques whereby a first exposure obtains pixel measurements for a first subset of pixels of a pixel array, using a first reference signal. For a second exposure, the first subset of the pixels, e.g., every second line of the pixel array, are set to a “hold” state, so that values obtained from the first measurement are maintained. A second exposure using a second reference signal is performed for a second subset of the pixels. The first and second reference signals may have different phase shifts relative to a signal modulating an optical signal being measured. The result is an array of pixels in which the first and second subsets hold results of the first and second exposures, respectively. These pixel values can then be read out all at once, with certain calculations being performed directly as pixel values are read from the pixel array.

    Abstract: An example time-of-flight device may include an emitter component configured to emit a plurality of modulated signals toward an object during a transmission window, wherein the plurality of modulated signals emitted during the transmission window are to be used to determine a single distance measurement associated with the object and the time-of-flight device. The time-of-flight device may include a control component configured to cause, via the emitter component, emission of a first modulated signal and emission of a second modulated signal, of the plurality of modulated signals, toward the object, wherein the first modulated signal is emitted during a first portion of the transmission window and has a first phase of a plurality of preconfigured phases, and wherein the second modulated signal is emitted during a second portion of the transmission window and has a second phase of the plurality of preconfigured phases; and cause, using the emission of the first modulated signal and the emission of the second modulated signal during the transmission window, an emulation of a transmission of a measurement signal that has a measurement phase defined based on the first phase and the second phase, wherein the measurement phase is different from the first phase and the second phase.
