| Abstract: | A systematic approach is developed for the implementation of discrete Hopfield neural network(DHNN)and associative memory(AM) neural network using switched current(SI)integrated circuit techniques Three neuron cells,which are multiple input transconductor,switched current delay(SID)and programmable current comparator(PCC)used for the implementation of DHNN,are introduced A switched current AM circuit architecture is also presented The proposed SI neural circuits is capable of operating at power supply down to 3 3 V,and it is suitable for VLSI process |
