摘要

This paper presents results on comparisons and advantages thatallow mixed analog-digital circuit design on SOT (sea-of-transistors)array methodology. The aim is to present the advantages of using asuitable trapezoidal association of digital transistors, to improve theoutput conductance. Noise considerations are also presented to furtherjustify the need for several transistors in the association, improvingthe characteristic noise of short-channel transistors. Severalstructures of TAT (trapezoidal association of transistors) and singletransistors of electrically equivalent sizes were implemented to allowbetter comparison and to evaluate noise performance. The SOT unittransistors are on a fixed-size array and experimental results obtainedare herein shown for 1.0 μm digital technology
