Analog VLSI Circuits for Visual Motion-Based Adaptation of Post-Saccadic Drift

Abstract:

Using the analog VLSI-based saccadic eye movement system previously developed in our laboratory (Horiuchi, Bishofberger, and Koch, 1994), we are investigating the use of biologically realistic error signals to calibrate the system in a manner similar to the primate oculomotor system. In this paper we introduce two new circuit components which are used to perform this task, a resettable-integrator model of the burst generator with a floating-gate structure to provide on-chip storage of analog parameters and a directionally-selective motion detector for detecting post-saccadic drift.
