Je. Varrientos et al., A CURRENT-MODE CELLULAR NEURAL-NETWORK IMPLEMENTATION, IEEE transactions on circuits and systems. 2, Analog and digital signal processing, 40(3), 1993, pp. 147-155
A compact and efficient current-mode circuit implementation for a cell
ular neural network is presented. The implementation presented consist
s of current amplifiers, simple current mirrors, simple current source
s and transconductors. Experimental results from first generation CMOS
monolithic prototypes with fixed connection weights show the feasibil
ity of the proposed implementation by successfully performing edge det
ection and noise removal image processing.
