Abstract : A trainable adaptive threshold logic gate is described. A review of basic theory of threshold logic is presented along with a description of a training technique. Capacitors capable of exhibiting long term analog memory are used in the physical realization of an adaptive threshold logic gate. A description of both the capacitive analog memory and the trainable gate is given. Training results of the adaptive threshold device are exhibited for ten different linearly separable switching functions. Some practical discrepancies between ideal operation and circuit operation are discussed. Suggestions for future studies and circuit improvements are given. (Author)
