摘要

In this paper, we present a compact CMOS VLSI design for recursive neural networks with the capability of hardware annealing. Locally-connected recursive neural networks are a class of analog nonlinear networks which can solve many important optimization, and signal processing problems and is suitable for VLSI implementation because of its low demand on inter-cell connections. Hardware annealing, which is a paralleled version of effective mean-field annealing in analog networks, is a highly-efficient method to find global optimal solutions of recursive neural networks. A two-neuron prototype chip to demonstrate the functionality of hardware annealing is designed, analyzed and implemented in 2.0 /spl mu/m CMOS technology using mixed-signal design methodology through MOSIS. For circuit reliability and compactness, a unit current of 6 /spl mu/A is used. The cell density is 505 cells/cm/sup 2/ and the cell time constant time is designed to be 0.3 /spl mu/s. Laboratory experimental results to show the behavior of this two neuron chip was produced with annealing control signals from a function generator.
