  • Visual cortical circuit apparatus, visual cortical imitation system and object search system using visual cortical circuit apparatus
    Patent number: 9798971
    Abstract: Provided us a visual cortical circuit apparatus comprising: a current mirror unit which uses a transistor as a current source to generate a current having the same size as that of a reaction; a transconductance unit which takes, as an input, the current generated by the current mirror unit and outputs a voltage using a transconductance; and a buffer unit for converting the voltage output from the transconductance unit into a current and buffering the current.
    Type: Grant
    Filed: February 3, 2016
    Date of Patent: October 24, 2017
    Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
    Inventors: Il Song Han, Woo Joon Han
