Resistive-insulated-gate arrays and their applications - An exploratory study

A resistive-insulated-gate electrode with a voltage gradient applied along it has many uses. In this paper we present an exploratory investigation of a number of novel circuits in which the foregoing forms the backbone. We concentrate on three areas of application, namely steering circuits for electronic displays, analog-digital conversion and light-pattern scanning. Although we concentrate mainly on principles of operation, we also derive limits for salient characteristics, e.g., scanning speed, resolution. We do this with the aid of expressions based on certain simple models which have been verified by experiment.
