    Abstract: A sensor array arrangement for a time of flight measurement system is disclosed. The arrangement includes a plurality of pixels and circuitry. The plurality of pixels are configured such that a first plurality of pixels receive a first reference signal and a second plurality of pixels receive a second reference signal. The first and second reference signals are phase shifted with respect to each other. The circuitry calculates depth information by combining information from first and second pixel sensor signals. The first pixel sensor signal is based on the first reference signal. The second pixel sensor signal is based on the second reference signal.

    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.
