Circuit for logical-binary functions using MOS floating-gate devices

We have designed a logical external configuration circuit in which a highly-functional device called Neuron MOS Transistor (vMOS) is utilized as a key component. A dramatic reduction in the number of transistors as well as in complexity of interconnections has been achieved by the new circuit configuration using vMOS. In this work, simulations of our circuit of logical external configuration are presented using PSpice and we included the elimination of input-stage D/A converter like proposal to future. This circuit is able to represent the logic functions: AND, OR, NAND, NOR, Exclusive-NOR, Exclusive-OR, among others, with a 4-bits input option.
