Design and Simulation of Fuzzy System Using Operational Transconductance Amplifier

Conference paper
Part of the Smart Innovation, Systems and Technologies book series (SIST, volume 31)

Abstract

In this paper a well defined method for the design of fuzzy system using operational transconductance amplifier was discussed. This paper also presents the various types of operational transconductance amplifier: simple OTA, fully differential OTA and Balanced OTA. Proposed model of fully differential OTA and balance OTA is illustrated, out of which balance OTA is the best. Fuzzy system includes fuzzification of the input variables, application of the fuzzy operator (AND or OR) in the antecedent, implication from the antecedent to the consequent, aggregation of the consequents across the rules, and defuzzfication. The fuzzy system (including all blocks) for estimating risk involved in an engineering project has been designed, exhibits a gain of 36.24 dB, input resistance with 44.13 kΩ, output resistance with 2.163 kΩ, CMRR with 47.68 dB, slew rate with 0.6 V/µs and power dissipation with 197 W.
