Abstract: This paper presents the proposed circuit for the designing of the Gaussian membership function using electronic devices like metal oxide semiconductor field effect transistor (MOSFET), operational amplifier (OPAMP) in ORCAD. Proposed circuit includes concepts of current mirror and current sink. In the proposed circuit we can also have S and Z membership functions by varying various voltages.

Keywords: Metal oxide Semiconductor Field Effect Transistor, Operational Amplifier, Fuzzy System, Membership Functions, Current Mirror, Current Sink.
