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. In the letter a voltage-input current-output membership function circuit is proposed. The characteristic of this building block is tunable and is useful for current-mode analogue fuzzy hardware. The proposed circuit was designed by using 3.5μm CMOS design rules, and its operations have been confirmed using PSPICE simulations.
