Research was conducted on a high speed, ruggedized, miniature, digital voltmeter utilizing the field effect technique to accomplish analog to digital conversion. The practicality of a field effect analog to digital converter was investigated and attempts were made to incorporate such a device into a digital voltmeter system. Since the field was the asic concept around which the rest of the system was to be designed, much time was spent on fundamental investigati n into the types of materials available for this application and the design of the proper geometry of the field. Due to the limitations of present day materials and components, the cost of fabricating a field effect voltmeter that will provide analog to digital conversion at rates in excess of 10 mc is so high that it does not seem practical at this time. In addition, the uncertainty of the fabrication of the field and the enormous amount of circuitry required to make the field effective are quite out of line with what could be considered reasonable for a panel type meter.
