A neuromorphic MOS circuit imitating jamming avoidance response of Eigenmannia

In this paper, we implement a model of an electric fish, Eigenmannia, that detects frequency differences between the individuals, on analog CMOS circuits. The circuit's fundamental function is equivalent to a conventional “phase frequency comparator”. The circuit consists of five elemental cell units that implement neural networks of the electric fish. Using a simulation program of integrated circuit emphasis (SPICE), we demonstrate that the proposed circuit can detect the frequency difference.
