Imec has developed a compact, highly linear 3.2 giga-sample-per-second (GSps) RF-sampling ADC that uses ring amplification (ringamp). The ADC has a record low power consumption of 61.3mW and supports multiband operation and massive MIMO implementation – two key features of future 5G base stations. A second power-efficient ringamp-based ADC – reconfigurable between 6 and 600Msps ...
