Abstract
In a general way, Current scaling DACs are used in wireless communication systems. But there are degradations of important factors because of mismatch of current source corresponding to high resolution. To solve the problem, Calibration methods are researched lately. Mismatch of current source is corrected by Calibration method and then corrected current values are delivered to Core DAC. As a results, Degradations of important factors that produced by increment of non-linearity are suppressed by calibration method.
