A Robust, Wide-Temperature Data Transmission System for Space Environments

The State-of-the-Art in Rad-Hard and Wide-Temperature IC Fabrication is briefly reviewed, then extensions to the design range of an existing HTSOI process are described. NULL Convention Logic is described in relation to temperature and radiation insensitivity. Finally, an 8-bit data transfer system is described and simulated using NCL and the HTSOI process. The system shows good results over a 400 degrees C operating range.
