New Velocity Tuned Filter Using Nanoelectronic Architecture

Motion computation is a major concern for real-time vision machines or retinas that require tiny, energy efficient, and fast circuitry. This concern has been addressed through the use of velocity tuned filters, which are a major part of motion computation circuitry. However, conventional velocity tuned filters have limitations in area, power, and speed for real-time motion computation. Hence, we propose a new velocity tuned filter with tiny, energy efficient, and fast circuitry. Our new velocity tuned filter employs nanoelectronic architecture based on quantum dot arrays on resonant tunneling diodes. The new velocity tuned filter is superior to existing velocity tuned filters in area, power and speed. Additionally, analysis of the system demonstrates that it is asymptotically stable in the specific region where f′(Sn,m)≥0.
