significantly restricts low-voltage operation since it results in a low ON -to- OFF current ratio at low supply voltages. This paper investigates extremely low-power circuits based on new Si/SiGe ...

You may run into a second limitation of business-oriented computers -- relatively low power supply capacities. A graphics card is similar to a computer in that it uses power to manipulate data.

A two-part series that covers the basics of power supply design in the context of industrial functional safety.
