Optical neural-net analog-to-digital converter
Ju-Seog Jang, Sang-Yung Shin, Soo-Young Lee · Optics Letters · 1989
A parallel analog-to-digital converter with neuronlike elements is designed and optically implemented. Its operation principle is the simultaneous estimation of bit values for a given analog input. Architecture of the proposed analog-to-digital converter is simpler than that of an earlier one designed by the energy-minimization technique, and its digital output is independent of the initial state.
