Analog VLSI circuits for visual motion-based adaptation of post-saccadic drift

Abstract

Using the analog VLSI-based saccadic eye movement system previously developed we investigate 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.
