A Current Switch of Current-steering DAC Output Stage

摘要：

When DAC is applied to communication field, it is generally necessary to have a good dynamic performance. However, nonlinear distortion of output stage current switch has a potent effect on DAC as a whole. The approach proposed in this paper aims to improve on distortion in output stage. As a result of practical measurement, clock frequency is 200MHz, and SFDR of the DAC with a data frequency of 20MHz is 83dBC.
