Improving the functionality of the semiconductor matrix receiver of optical radiation

摘要

The work is devoted to improving the functionality of the semiconductor integrated matrix receiver of visible range radiation with a capacitor multichannel analog-to-digital Converter on a chip. Reading is carried out by a column capacitor of sequential approximation with a digital-analog converter based on switched capacitors DAC with charge summation. In the matrix receiver, the occupied area and the dissipated power of the semiconductor chip are significantly reduced with the simple implementation of capacitor structures by the technology of semiconductor micro-devices manufacturing.
