Analog-to-digital converter based on RSFQ technology for radio astronomy applications

Abstract: We are developing an analog-to-digital converter (ADC) based on rapid single-flux quantum technology for radio-astronomic spectroscopy applications where very wide bandwidth is required and relatively small resolution is sufficient. The ADC consists of periodic-flash comparators, a demultiplexer and output drivers; and is sufficiently simple to be implemented on a single chip using a conventional 2–3 μm Nb trilayer technology. A 2-bit ADC has been designed for operation at 16 GHz of the sampling frequency. All… Show more
