Research Notes


A current-mode MOS neuron circuit with 4-bit programmable weights is presented by using CMOS technology. The weights of the neuron have high resolution and also can easily be digitally stored. The resolution can be extended into high levels such as 8-bit, etc. by the design methodology presented in this paper. The operational 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.
