Analog Motion Detection Circuits Using Simple Edge Detection Circuits Based on the Vertebrate Retina

We proposed in this research novel analog motion detection circuits using previous proposed edge detection circuits based on the vertebrate retina, which is characterized by the wide dynamic range, low power consumption and compact structure. The structure of the proposed motion detection circuit becomes compact, which is designed mainly using 6 n-channel metal oxide semiconductor (nMOS) transistors and 2 capacitors. The simulation results with the simulation program with integrated circuit emphasis (SPICE) showed that the proposed circuit can generate the motion signal. By using this circuit, we can expect to realize the visual sensor in one chip, which is characterized by the high resolution, wide dynamic range and low power consumption.
