Abstract :
The membership function circuit (MFC) is used in the input parts of analogue fuzzy hardware systems. The fuzzy hardware can execute singleton fuzzy control algorithms. The authors propose a voltage input current-output membership function circuit. The characteristic of this building block is tunable and is useful for current-mode analogue fuzzy hardware. The proposed circuit was designed by using 3.5 mu m CMOS design rules, and its operations have been confirmed using PSPICE simulations.
