An Analog Implementation of Early Visual Processing in Insects

  title={An Analog Implementation of Early Visual Processing in Insects},
  author={Moini and Yakovleff and D. and Kamran Eshraghian and Robert E. Bogner},
An analog VLSI implementation which mimics the early visual processing stages in insects is described. The system is composed of sixty parallel channels of integrated photodetectors and processing elements. It serves as the front end processor for a motion detection chip. The pliotodetection circuitry includes p-well junction diodes on a 2pm CMOS process and a logarithmic coinpression to increase the dynamic range of the system. The processing elements consist of an analog differentiator behind… CONTINUE READING
