Guerra-Gómez M.A. Duarte-Villaseñor G. Reyes-Salgado Ingeniería MOSFET Fuzzy sets circuit sizing analog circuits fuzzy set intersection A fuzzy sets intersection procedure to select the optimum sizes of analog circuits composed of metal-oxidesemiconductorfield-effect-transistors (MOSFETs), is presented. The cases of study are voltage followers (VFs) and a current-feedback operational amplifier (CFOA), where the width (W) and length (L) of the MOSFETs are selected from the space of feasible solutions computed by swarm or evolutionary algorithms. The evaluation of three objectives, namely: gain, bandwidth and power consumption; is performed using HSPICETM with standard integrated circuit (IC) technology of 0.35¿m for the VFs and 180nm for the CFOA. Therefore, the intersection procedure among three fuzzysets representing "gain close to unity", "high bandwidth" and "minimum power consumption", is presented. The main advantage relies on its usefulness to select feasible W/L sizes automatically but by considering deviation percentagesfrom the desired target specifications. Basically, assigning a threshold to each fuzzy set does it. As a result, the proposed approach selects the best feasible sizes solutions to guarantee and to enhance the performances of the ICs in analog signal processing applications. 2012 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47423208015 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.3 Vol.10 |
