摘要： A pixel cell includes a pixel set with a plurality of pixels, with each pixel of the pixel set being configured to capture optical information incident upon the respective pixel and generate electrical information representative of the optical information. The pixel cell further includes a readout circuit which is configured to manage collection and output of the electrical information from each pixel of the pixel set and to operate the pixel set in a global shutter mode and in a rolling shutter mode of operation. In the global shutter mode, the electrical information from each pixel is combined for generating a global shutter output signal, while in the rolling shutter mode, the electrical information from each pixel is used to generate individual rolling shutter output signals.

摘要： An image sensor system has a pixel array with a plurality of pixels, each of the pixels comprising a photodiode, a pixel buffer and a transfer gate coupled between the photodiode and an input of the pixel buffer. A voltage supply block is configured to generate a pixel supply voltage from an input voltage based on a first reference voltage and to provide the pixel supply voltage to the pixel array. A calibration processing block is configured to determine an average pixel signal based on an average of individual pixel signals at outputs of the pixels of the pixel array and to determine a correction value based on the average pixel signal and a reference pixel signal. A correction processing block is configured to determine the first reference voltage based on a combination of a second reference voltage and the correction value.

摘要： A pixel with enhanced quantum efficiency comprises a semiconductor body that has a first surface configured as an entrance surface and a light capturing region configured for capturing light that is incident on the first surface. The pixel further comprises a structured interface, isolation layers on at least two surfaces of the semiconductor body that are perpendicular to the first surface, and a filter element that is arranged at a distance from the first surface such that light that is incident on the first surface at an angle of incidence smaller than a critical angle impinges on the filter element.

摘要： An analog-to-digital converter (110) comprises an analog signal input (122) for receiving an analog signal and an amplifying stage (160) configured to generate a set of N amplified analog signals, where N is an integer≥2. The set of N signals have different gains. The ADC has a ramp signal input (121) for receiving a ramp signal and a clock input (143) for receiving at least one clock signal. A comparison stage (120) is connected to the set of amplified analog signals (SigG1, SigG2) and to the ramp signal input (121). The comparison stage (120) is configured to compare the amplified analog signals with the ramp signal to provide comparison outputs during a conversion period. A control stage is configured to control the counter stage (140) based on the comparison outputs and a selection input indicative of when at least one handover point has been reached during the conversion period.
