A Neuron MOS Transister has been developed, as new functional device which behaves more intelligently than a mere switching device. This functional device calculates weighted sum of all input signals at the gate level, and turns "on" or "off" based on the result of such a weighted sum operation. Making use of this powerful function, a number of interesting circuit applications have been explored. One of the most striking features of Neuron MOS applications is the realization of a variable logic circuit. This circuit can represent any logic function AND, OR, NAND, NOR, Exclusive-OR, Exclusive-NOR, etc., by adjusting external control signals without any changes in the hardware configuration. The circuit allows us to build real-time reconfigurable systems. In this paper, we propose a design of the universal variable logic circuit which represents 16 binary logic function in 2-variable, and another variable logic circuit which represents 6 binary logic function (AND, OR, NAND, NOR, Exclusive-OR, Exclusive-NOR) in any variable. The circuits are designed with a graphcal method which we call Floating-Gate Potential Diagram. PSPICE simulation results of the circuits are also presented.
