The Cryogenic Temperature Behavior of Bipolar, MOS, and DTMOS Transistors in Standard CMOS

Edoardo Charbon, Harald Arjan Robert Homulle, Fabio Sebastiano

Both CMOS bandgap voltage references and temperature sensors rely on the temperature behavior of either CMOS substrate BJTs or MOS transistors in weak inversion. Bipolar transistors are generally preferred over MOS transistors because of their lower spread ...

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 ...
