Abstract
An innovative readout circuit for a pixel detector, for example a solid-state X-ray pixel array, The invention includes a bank of successive approximation ADCs with a DAC in a feedback path. The integral non-linearity of the DACs and of the ADC is reduced to very low levels by providing a common resistive ladder for all the channels. In this way, the conversion law is sensibly the same for all the ADC, thus avoiding stripes or artefacts on the acquired image.
