| Abstract | Abstract — A 14-bit digital-to-analog converter based on a fourth-order multibit sigma–delta modulator is described. The digital modulator is pipelined to minimize both its power dissipation and design complexity. The 6-bit output of this modulator is converted to analog using 64 current-steering cells that are continuously calibrated to a reference current. This converter achieves 85-dB dynamic range at 5-MHz signal bandwidth, with an oversampling ratio of 12. The chip was fabricated in a 0.5-"m CMOS technology and operates from a single 2.5-V supply. Index Terms — Current calibration, digital-to-analog conversion, mixed analog–digital integrated circuits, multibit modulators, pipelined adders, sigma–delta modulation. I. |
