Inversion/non-inversion reconfiguration scheme for a 0.18 μm CMOS process optically reconfigurable gate array VLSI

To date, various optically reconfigurable gate arrays (ORGAs) have been developed to realize both fast reconfiguration and numerous l'econfiguration contexts. Optically differential reconfigurable gate arrays (ODRGAs) present advantageous capabilities compared with other ORGAs: they have increased the reconfiguration frequency per unit of laser power and have reduced optical configuration power consumption. On the other hand, dynamic optically reconfigurable gate arrays (DORGA) can realize the highest gate density, but an important disadvantage of DORGAs is that their reconfiguration frequency is lower than that of ODRGAs and their optical configuration power consumption is greater than that of ODRGAs. Therefore, a novel inversion/non-inversion dynamic optically reconfigurable gate array has been developed, adopting only the best attributes from both architectures. This paper presents an inversion/non- inversion implementation for a newly fabricated 0.18 μm CMOS process optically reconfigurable gate array VLSI.
