Sensitivities analysis of the current mirrors with MOS-FET for the basic FUZZY logic gates/circuits

The paper presents a comprehensive approach of the fuzzy logic gates/circuits from both technological and circuit analysis point of view, using SPICE simulation, based on computing the sensitivities of current mirrors with n and p-channel MOS-FET (using units or tens microns for L and W parameters). CMOS technology has been recognized as the technology for implementing fuzzy logic gates/circuits in the current mode, which offers a high versatility for different fuzzy logic operations, low power dissipation and high integration density. The basic units of fuzzy logic gates/circuits are the current mirrors with single and/or multiple outputs, usually designed and fabricated in 5-10 microns CMOS technology.
