Psychology Press eBooks · 2013
There have been many researches reported in the area of analog neural network hardware implementations for various applications of adaptive signal processing [3-6]. In our work. the atlalog VLSI neural network processor chip was designed and fabricated for communication receiver applications. Each programmable synapse cell is made of a compact atld wide-range analog multiplier circuit. The arrays of the input neurons and the output neurons are optimized for large current-driving capability. The neural network processor chip perfonns the feedforward operation and a companion DSP board executes the back-propagation algoritluns.
