Keywords:Self-Cascode, Analog Characterization, Silicon-On-Insulator, Composite Transistor
This paper proposes a curve extraction method for I-V curves and analog figures-of-merit of self-cascode MOSFET associations (SC) using a code that exploits I-V curves of single transistors as input. The method was validated by using experimental measurements of fabricated SC and the very single transistors that compose them. The results indicate a very low error between the SC generated by the code and the measured reference for operation in saturation regime and above threshold voltage, for both the I-V curves and their derivatives. This method is then valid for the assessment of the SC structures in new technologies, avoiding experimental dedicated layouts or complex set-ups.
