Abstract
In the recent decade, different researchers have performed hardware implementation for different applications covering various areas of experts. In this research paper, a novel analog design and implementation of different steps of fuzzy systems with current differencing buffered amplifier (CDBA) are proposed with a compact structure that can be used in many signal processing applications. The proposed circuits are capable of wide input current range, simple structure, and are highly linear. Different electrical parameters were compared for the proposed fuzzy system when using different membership functions. The novelty of this paper lies in the electronic implementation of different steps for realizing a fuzzy system using current amplifiers. When the power supply voltage of CDBA is 2 V, it results in 155 mW, power dissipation; 4.615 KΩ, input resistance; 366 KΩ, output resistances; and 189.09 dB, common-mode rejection ratio. A 155.519 dB, voltage gain, and 0.76 V/μs, the slew rate is analyzed when the power supply voltage of CDBA is 3 V. The fuzzy system is realized in 20 nm CMOS technology and investigated with an output signal of high precision and high speed, illustrating that it is suitable for real-time applications. In this research paper, a consequence of feedback resistance on the adder circuit and the defuzzified circuit is also analyzed and the best results are obtained using 100 K resistance. The structure has a low hardware complexity leading to a low delay and a rather high quality.

Summary
Circuits produce output based upon input stimulus. There are advantaged crossover points in both circuit types where one approach is better than another. The increase in trend towards low power systems and high performance leads to innovative design methodology [1]. This helps in meeting the stringent system requirements and many of them are performing stream data processing. To overcome this problem Integrated Circuits (IC) technology helps in producing chips using a different number of transistors. There are some limitations of one level of the design to compensate for the shortcomings at higher levels These limitations occur due to inherent constraints in the technology specifying speed, power, performance, throughput, complexity, etc. There are numerous novel active elements established out of which numerous of them are just theoretical components that offer further research
