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.

An imaging system may include a modulation component to provide a modulation signal. The imaging system may include an illumination component to receive the modulation signal and emit a modulated optical signal based on the modulation signal, and provide an electrical illumination signal. The electrical illumination signal may be an electrical representation of the modulated optical signal emitted by the illumination component. The imaging system may include an electrical mixer to receive the electrical illumination signal and the modulation signal, multiply the electrical illumination signal and the modulation signal in order to form a mixed signal, filter the mixed signal in order to form a filtered mixed signal, and output, based on the filtered mixed signal, a calibration signal associated with calibrating the imaging system.

The present disclosure relates to an imaging apparatus. The imaging apparatus comprises a pixel array. The pixel array comprises a first pixel comprising a first radiation-sensitive region and at least one associated charge storage region for collecting electrical charges from the first radiation-sensitive region. The pixel array also comprises a second pixel comprising a second radiation-sensitive region and at least one associated charge storage region for collecting electrical charges from the second radiation-sensitive region. Furthermore, the imaging apparatus comprises control circuitry configured to generate a common compensation signal being common to the first and second pixels. The common compensation signal mitigates a saturation of the respective charge storage regions of the first and second pixels.

A limiting amplifier includes a multiplicity of cascaded amplifier stages for amplifying an input signal for the amplifier. A further amplifier stage is supplied with a reference signal. On the basis of an output signal from the further amplifier stage, a control signal for adjusting a gain of at least one of the cascaded amplifier stages is produced.
