Trapezoidal association of transistors for mixed analog-digital circuits design on SOT array

Abstract

This paper presents advantages of CMOS trapezoidal association of transistors (TAT) aiming at semi-custom mixed analog/digital circuits design on Sea-Of-Transistors (SOT) array. Several types and structures of transistors were implemented to allow better comparison with the association of transistors of same size. The SOT unit cells are on fixed size array and experimental results are shown for a 1.0 /spl mu/m digital technology.
