A segmented DEM technique that allows an efficient tradeoff between encoder complexity and the number of unit current-steering cells enables a 150MS/s DAC with greater than 83dB of SFDR across the Nyquist band. The 0.18μm CMOS IC has an active area of 3mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and dissipates 127mW.
