Abstract:
This article presents a spur-suppressed background calibration technique for high-speed current-steering digital-to-analog converters (DACs), based on a paired current source (CS) switching scheme. In conventional background calibration, periodic switching of CSs to and from the calibration mode introduces unwanted glitches that appear as spurious tones. The proposed technique introduces an …
