Design techniques for a stable operation of cryogenic field-programmable gate arrays

Edoardo Charbon, Harald Arjan Robert Homulle

In this paper, we show how a deep-submicron field-programmable gate array (FPGA) can be operated more stably at extremely low temperatures through special firmware design techniques. Stability at low temperatures is limited through long power supply wires ...
