摘要

提出了一种基于运算跨导放大器(OTAs)的模拟CMOS模糊运算电路(隶属函数电路、最大电路、最小电路和去模糊电路)的设计。在采用标准5 /spl mu/m CMOS设计的情况下，通过SPICE仿真验证了其运算速度和精度。作为应用，利用所提出的电路合成了一个3/ sp1倍/3单态模糊控制器。仿真结果表明，该控制器可以很容易地实现1 MFLIPS(每秒模糊逻辑推理)数量级的运算速度。

A design of analog CMOS fuzzy inference circuits using OTAs

A design of analog CMOS fuzzy operational circuits (a membership function circuit, a maximum circuit, a minimum circuit and a defuzzifier circuit) based on operational transconductance amplifiers (OTAs) is presented. SPICE simulations are given to show their operation speed and accuracy under the assumption that the standard 5 /spl mu/m CMOS design is used. As an application, a 3/spl times/3 singleton fuzzy controller is synthesized using the proposed circuits. The simulation of this controller showed that the operation speed of the order of 1 MFLIPS (fuzzy logical inference per second) is easily realizable.<>
