Abstract
Monolithic analog-to-digital (A/D) and digital-to-analog (D/A) converters suffer from the limited accuracy of the available circuit compensators. A self-calibration method allows the correction of the linearity errors of binary-weighted current-source arrays commonly used in high-speed converters. To achieve high-calibration accuracy a modified dual-slope method is used. This makes it possible to implement A/D and D/A converters with a resolution of 14 b or more at a conversion time of less than 15 μs
