Abstract
An analogue to digital converter is provided for digital imaging devices, in which a pixel column is sampled by a respective capacitor. In a reset phase of operation, each pixel in the row under consideration is reset, and an operational amplifier operating in a voltage follower mode is coupled to all the sampling capacitors in parallel to obtain the reset values of the pixels sensors of that row, and the in an imaging phase of operation, the inverting input of the operational amplifier operating in a comparator mode is coupled to each capacitor in turn after activating the respective pixel sensor, while exposing the non inverting signal to an analog ramp reference voltage so that the timing of the toggling of the operational amplifier reflects the value of the pixel under consideration, corrected for the reset value.
