Abstract: A current-mode MOS neuron circuit with 4-bit programmable weights is presented using CMOS tetchnology. The weights of the neuron have high resolution and also can easily be digitally stored. The resolution can be extended into higher levels such as 8-bits, etc. by the design methodology presented in this paper. The operation principle of the neuron is discussed. Circuit simulation has been made by use of SPICE Ⅱ. The results give a good agreement for the design requirements. -
