METHOD OF OPTIMIZING CMOS IDAC LINEARITY PERFORMANCE USING GOLDEN RATIO

摘要

A layout method for a current source array. A digital-to-analog converter (DAC) includes a plurality of complementary metal-oxide-semiconductor (CMOS) devices. Current sources for the CMOS devices are uniformly arranged in a one-dimensional array. The spacing between the current sources in the one-dimensional array is determined using a golden ratio.
