The main advantage of the proposed circuits is the capability for the production of all Trapezoidal, Gaussian, S and Z shapes, simultaneously. This objective has been achieved at the first step by means of two interconnected differential pairs which generate Gaussian, S and Z shapes. Thereafter, with the help of an improved Min/Max circuit, the Trapezoidal shape with sharp edges has been constructed. The circuits are designed in a way to produce all shapes with the feature of full programmability for slope, core, and height. These features, along with small active area and low power consumption, qualify this work to be repeatedly used in Fuzzy Logic Controllers (FLCs). Post-layout simulation results for TSMC 0.18µm CMOS technology confirm the correct behavior of the designed circuits. Based on the results, the power consumption of the whole structure is 54µW from a 1.8V power supplyV tem članku je obravnavana zasnova nove prilagodljive strukture za fuzzy funkcijski generator (MFG). Glavna prednost predlaganih vezij je možnost hkratne izdelave vseh trapeznih, Gaussovih, S in Z oblik. Cilj je bil v prvi fazi dosežen z dvema povezanima diferencialnima paroma, ki ustvarjata Gaussovo, S in Z obliko. Nato je bila s pomočjo izboljšanega vezja Min/Max izdelana trapezoidna oblika z ostrimi robovi. Vezja so zasnovana tako, da omogočajo izdelavo vseh oblik z možnostjo popolnega programiranja naklona, jedra in višine. Te lastnosti, skupaj z majhno aktivno površino in majhno porabo energije, omogočajo, da se to delo uporabi v fuzzy logičnih krmilnikih (FLC). Rezultati simulacije po izdelavi za tehnologijo TSMC 0,18 µm CMOS potrjujejo pravilno obnašanje zasnovanih vezij. Na podlagi rezultatov je poraba energije celotne strukture 54 µW pri napajalni napetosti 1,8VTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaStrokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale
