In this paper we present analog very large-scale integrated(VLSI) circuits that perform the selection process for attentivevisual processing. These circuits use excitatory feedback ina winner-take-all computation to produce a hysteresis in theselection from one location to the next. We present several alternativeforms of excitation that can be used to enhance surrounding regionsof the presently attended location. Each form of excitation isdiscussed and experimental results from a one-dimensional arrayare presented. We also demonstrate the performance of these circuitswithin a system that receives optical inputs and outputs a singlevoltage that encodes the position of attention. The system demonstratesthe potential use of these excitatory feedback circuits for electronictracking of a stimulus within a noisy environment.
