Title: Low Power High Speed Digital Signal Isolator
Agency: NASA
Contract: NAS3-02186
Award Amount: $69,970.00
 

Abstract:

Highly-sensitive linear spin-valve sensors combined with NVE's patented GMR isolator technology will be used to develop miniature, low power, high speed, radiation-hard, digital isolator devices for space and other commercial applications. The proposed linear mode spin-valve digital isolators will overcome the shortcomings of the present latching mode spin-valve digital isolators. The devices can be designed to work either in the unipolar mode or bipolar mode. If operating in the unipolar mode, the devices will not only be fully pin-for-pin compatible with optocouplers but also have superior performance with regard to cost, size, power consumption (<35 mW), bandwidth (DC to 1 GHz) and radiation tolerance. If operating in the bipolar mode, the devices will significantly improve NVE's present latching mode digital isolators with much faster speed (>400Mbd) and at least 80% less power consumption. This Phase II proposal is directed towards designing, fabricating and optimizing single/multi-channel digital signal isolator devices. The linear spin-valve sensors used in these devices will be based on the Phase I result. Prototype, radiation hard, low power, high speed, miniature digital isolator devices, that meet space and other commercial requirements will be demonstrated, and these prototypes will be ready for Phase III commercialization.
