How about electronics operating at 50 degK? The James Webb Space Telescope (JWST) will have electronics operating in taht regime.

In terrestrial electronics we think "ambient temperature >> box temperature >> component temperature >> junction temperature" and must find cooling methods to keep the latter below some key figure for the device, such as 100 deg C (pick your own number!), all this in the face of heat generated in the device. In the cold space case, we have internal heat generation working in our favour. Of cousre, cold-start devices must start (or restart) at the low ambient of space (the -271 degrees C or -456 F stated) but once powered up there is the same rising temperature from ambient to junction. One might speculate that "-140 deg C" devices would work if they always remain powered. The need would now seem to be box insulation rather than cooling. But then there's the matter of facing the sun vs. deep in shadow...

How can one get in contact with either prof. Alan Mantooth or someone else in the team who worked on this amplifier ?

Congratulations to the team at Univ. of Arkansas. It is good to see silicon R&D for the Space industry. I am looking forward to see this type of amp working in the GHz range.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
