A means of VLSI current controlled weight setting in ANNs
Sandeep Kumar Singh, R.W. Newcomb, Perales Gómez, V. Rodellar · 2002
A means is given for setting the weights in BiCMOS VLSI realizations of analog neural networks of the Hopfield class. This is achieved by the use of a BJT 4-quadrant current multiplier for which one set of the multiplier's differential current inputs comes from a CMOS differential pair giving a neuron's output current from its input capacitor voltage and the other set of the multiplier's differential currents comes from a differential pair with its input being a weight setting voltage.
