Abstract
A four quadrant, analog multiplier circuit useful for MOS implementation of feedback/feedforward neural networks. The multiplier circuit uses only one op-amp and one pair of input MOS FETs. It becomes a multiplier/summer by the addition of only one additional pair of input FETs for each additional product to be summed and achieves the vector scalar product of 2 n-tuple vector inputs using only 2(n+1) MOS transistors.
