The neuron MOS transistor is a recently invented device with high functionality. In this paper, a systematic approach for designing four quadrant analogue multiplier with low supply voltage requirements realized by using neuron MOS transistors is discussed. This approach is based on a new macromodel of neuron MOS transistor proposed by authors, which is used as a means of design and verification. A low supply (±1.5 V) four quadrant analogue multiplier with large input dynamic range is proposed on the basis of the approach, and the simulation results are given to verify the theoretical analyses.
