Abstract

Full Circle Research, Inc. (FCR) proposes a Phase II Small Business Innovative Research (SBIR) program to continue to development of rad-hard precision voltage regulators (PVR) with the stability under tempertature and radiation required by space electronic systems. Stable voltage references are required for a variety of electronic systems in space, such as voltage regulators, high resolution A/D and D/A converters, etc. Previous approaches have been unable to provide the accuracy and radiation hardness required by space systems. Consequently, there presently is no PVR capable of meeting these needs. This program proposes to develop rad-hard PVR's based on a new concept invented by Mr. James P. Spratt of Full Circle Research, Inc. Two voltage references will be developed, with the first addressing the most widely used component in today's space systems, vis. The coltage regulator, and the second addressing the most demanding requirements, viz. wide word (16-18 bit) ADC's. The stability requirements of these two devices is discussed below, the advantages of a two stage development effort presented, and industry support for the effort demonstrated.
