摘要： An analog-to-digital converter for generating an output digital value equivalent to the difference between a first analog signal level (Vres) and a second analog signal level (Vsig) comprises at least one input for receiving the first analog signal level and the second analog signal level, an input for receiving a ramp signal and an input for receiving at least one clock signal. A set of N counters, where N≧2, are arranged to use N clock signals which are offset in phase from one another. A control stage is arranged to enable the N counters based on a comparison of the ramp signal with the first analog signal level (Vres) and the second analog signal level (Vsig). An output stage is arranged to output the digital value which is a function of values accumulated by the N counters during a period when they are enabled.

摘要： A pixel structure comprises a photo-sensitive element for generating charge in response to incident light. A first transfer gate is connected between the photo-sensitive element and a first charge conversion element. A second transfer gate is connected between the photo-sensitive element and a second charge conversion element. An output stage outputs a first value related to charge at the first charge conversion element and outputs a second value related to charge at the second charge conversion element. A controller controls operation of the pixel structures and causes a pixel structure. The controller causes the pixel structure to: acquire charges on the photo-sensitive element during an exposure period; transfer a first portion of the charges acquired during the exposure period from the photo-sensitive element to the first charge conversion element via the first transfer gate; and transfer a second portion of the charges acquired during the exposure period from the photo-sensitive element to the second charge conversion element via the second transfer gate.

A first buffer amplifier has an input connected to the sense node and an output connected to a sample stage operable to sample a value of the sense node. A second buffer amplifier has an input connected to the sample stage. Control circuitry operates the reset switch and causes the sample stage to sample the sense node while the photo-sensitive element is exposed to radiation. An array of pixels is synchronously exposed to radiation. Sampled values for a first exposure period can be read while the photo-sensitive element is exposed for a second exposure period.
