Analog CMOS Implementation of Diffusive Lotka-Volterra Neural Networks

Analog integrated circuits that implement oscillatory neural systems are very important tools for exploring and discovering novel forms of neural information processing. However, there are severe difficulties in constructing compact circuits with low-power dissipation, which prevents large-scale integration of oscillatory neural circuits. In this report, aiming at the development of oscillatory neural VLSIs, we present novel CMOS circuits that implement the Lotka-Volterra (LV) oscillatory systems.
