Abstract :
This paper presents the advantages of the trapezoidal association of transistor (TAT) technique for analog applications. Using only an association of fixed minimum size channel length transistors available on a Sea-of-Transistors (SOT), the TAT transistor achieves almost the same performance as its equivalent single transistor. Several structures of TATs and single transistors of electrically equivalent sizes, and operational transconductance amplifiers (OTA) in both methodologies were implemented to allow better performance comparisons. The experimental results obtained are herein shown for 1.0 μm digital technology
