Document Type and Number:
Japanese Patent JP3095798
Kind Code:
B2
Abstract:
PURPOSE:To improve a zigmoid function circuit, a weighting coefficient change circuit and a multiplication circuit, to improve the holding characteristics of electrochemical integral element at the time of positive propagation of the analog reverse propagation learning circuit, and to reduce the number of learnings to convergence. CONSTITUTION:In the analog reverse propagation learning circuit equipped with the positive propagation mode from an input layer to an output layer and a learning mode from the output layer to the input layer, a writing circuit 6 of a weighting coefficient change circuit is voltage control constant current circuit, and current proportional to an input voltage is obtained regardless of the internal voltage of the electrochemical integral element, and the current flows through analog switches 10 and 11 to an electochemical integral element 12. The suitability of the circuit constant by the simulation of a network is realized.
