The present disclosure relates to a detector device assisted by majority current, comprising a semiconductor layer of a first conductivity type, at least two control regions of the first conductivity type, at least one detection region of a second conductivity type opposite to the first conductivity type and a source for generating a majority carrier current associated with an electrical field, characterized in that it further comprises isolation means formed in the semiconductor layer and located between said two control regions, for deflecting the first majority carrier current generated by the first source between said two control regions and, hence, increasing the length of the first majority current path, reducing the amplitude of said first majority carrier current and, therefore, reducing the power consumption of the detector device.

The present invention relates to a method for driving a Time-of-Flight system for use with an illumination system being adapted to illuminate a scene with a modulated signal, the ToF system having an imaging sensor comprising at least one pixel, said pixel comprising taps driven by driving signals for detecting the modulated signal reflected from the scene, the method comprising, for each pixel, the steps of determining at least a first and a second pair of taps and driving each pair of taps to detect the reflected modulated signal during a predetermined number N of cycles of the modulated signal.

Method for driving a time-of-flight system

The invention relates to a majority current assisted detector device, comprising a semiconductor layer of a first conductivity type epitaxially grown on a semiconductor substrate, at least two control regions of the first conductivity type, at least two detection regions of a second conductivity type opposite to the first conductivity type, and a source for generating a majority carrier current in the semiconductor layer between the two control regions, the majority current being associated with an electrical field. The detection regions surround the control regions, thereby forming at least two taps. The device is configured for backside illumination and further comprises a well of the first conductivity type between the two detection regions for insulating the detection regions. The well comprises pixel circuitry elements.
