Abstract

A bidirectional associative memory using switched-capacitor (SC) filter techniques (SCBAM) is introduced and verified experimentally. The discrete-time equation that characterizes SC filter design is shown to be applicable in recalling m stored vector pairs that can be encoded in a correlation matrix M. The elements of M (and M^T) are represented by the values of the capacitor ratios used in the SCBAM. The SCBAM exhibits similar error correcting properties as the normal BAM, making it a good candidate for analog VLSI neural network implementations
