Abstract :
An asynchronous NULL Convention Logic (NCL) gate library is developed for applications in space environment with temperatures ranging from -196° C to 125° C with radiation exposure. To further improve radiation-immunity and temperature-stability dual high-density metal-insulator-metal (DMIM) capacitor-based delay elements (based on DMIM capacitors available in the IBM 9HP process) and an asynchronous Dual Interlocked Cell (DICE)-based DFF are introduced. Results from temperature simulation and radiation analysis are shown.
