.-- This paper describes the realization of a fuzzy controller which implements the simplified inference mechanism. CMOS analog circuits where signals are represented as currents are employed. However, the whole system is externally communicated through voltages, thus enabling simple interface with conventional control circuitry. I. INTRODUCTION The efficient realization of microelectronic systems for fuzzy logic-based control applications requires a careful choice of both the inference mechanisms and the circuit structures which implement each controller block. Among the various inference methods, the singleton or simplified method is the most adequate for hardware implementation, as well as offering enough freedom in the choice of antecedents and consequents to ensure efficient control. Concerning circuit design methodologies, current-mode techniques are especially suited for direct implementation of the basic fuzzy operators. Working in current-mode, dynamic range problems can be h...
