In this paper we present a 2GSps 12bit current steering digital-to-analog converter (DAC), in 100G Ft 0.18µm SiGe HBT technology. An improved switching sequence is proposed to compensate the gradient error and reduce the impact of cell-dependent-delay-variation. According to measured results, the test chip achieved a DNL/INL of 0.6/0.95 LSB respectively. The measured SFDR at low frequency is above...
