We developed two sets of prototype 4-Gsps 2-bit analog to digital converters (ADCs) with GaAs ICs for the realization of 4 GHz sampling in an ADC system for the Atacama Large Millimeter / submillimeter Array (ALMA). This consists of three sets of 12-Gbps decision circuits and 12-Gbps demultiplexers, and has the capability of sampling in a bandwidth of 6(More)
