A Novel Ganged DAC Solution for Multi-Site Testing
Joseph Kwan, Qing Song Zhao · Proceedings/Proceedings - International Test Conference · 2006
Testing of two current steering DACs for wireless communication devices with one digitizer in a single test to reduce test time and minimize the tester resources requirement is proposed. In addition, a new method to test the amplitude mismatch and phase mismatch between the two DACs is further developed on this proposed testing approach. The test results are presented and their applicability for production test is also discussed in this paper
