A time-multiplexed switched-capacitor circuit for neural network applications
J.E. Hansen, Jeanette K. Skelton, D.J. Allstot · 2003
A time-multiplexed switched-capacitor computational block with some neural network characteristics is under development. The goal of this work is not to model biological neuron qualities exactly but rather to emulate their primary characteristics to the extent necessary to solve some types of problems not suited to digital processing. The circuit operation and limitations on its performance are described. The circuit is intended to serve as a coprocessor to a digital microprocessor. Circuit functionality has been demonstrated with breadboarded circuit, and the circuit is currently being integrated.>
