摘要: Dynamic current copying is a technique that allows to continuously trim the single DAC-elements in background. One source at time taken out of DAC-array and compared with reference current. Then negative feedback loop established, and, by controlling DAC-element, or part thereof, suitable way, its forced equal When calibration completed, trimmed DAC-element switched back into continues take data processing. At same next put mode. all sources array are trimmed, cycle starts anew.
