摘要

提出了一种基于单态模糊控制算法的模糊逻辑函数发生器(FLUG)。通过引入新的t-norm操作,可以从原始算法中删除规范化操作。由于不需要分频器,FLUG可以简单地用电流模式CMOS电路实现。此外,为了解决电流模式下扇出数限制的问题,电压输入和电流输出隶属函数电路由运算跨导放大器组成,并用于FLUG的输入部分。由于电路简单,FLUG可以应用于模拟特定应用ic的基本单元。

A fuzzy logic function generator (FLUG) implemented with current mode CMOS circuits
A fuzzy logic function generator (FLUG) based on the singleton fuzzy control algorithm is proposed. The normalizing operation can be removed from the original algorithm by introducing a new t-norm operation. The FLUG can be simply implemented with the current mode CMOS circuits, because the dividers are not needed. Further, to solve the problem in the current mode with respect to the restriction of the fan-out number, voltage-input, and current-output membership function circuits are constituted of operational transconductance amplifiers (OTAs), and they are used in the input parts of the FLUG. Due to the simple circuitry, the FLUG can be applied to a basic cell for the analog application-specific ICs.<>
