Abstract :
Describes a project to design and build prototype analog early vision systems to determine how the advantages of analog VLSI, high speed, low power, and small area, can be exploited and its disadvantages, limited accuracy, inflexibility, lack of storage capacity, and long design times, can be minimized. This project explored three distinct circuit design styles for vision applications, continuous-time processing, charge-coupled devices, and switched capacitors. The overall effort and three chips are described
