Design of a linear 'sum-of-product' circuit for Boltzmann machines

A novel analog sum-of-product CMOS circuit which is based on a linear voltage-to-current converter is described. A synaptic cell is derived which features low current and small area, high linearity and high operation speed. It is well-suited to Boltzmann machines and any neural network with signed multivalued weights and binary neuron states.<
