One sector of the electronics
market continues to demand
faster and more powerful personal
computers. Another demands
a langer life from one battery
charge in ease of portable
computers: 2-3 hours is now a
minimum. Such demands are
not restricted to computers: they
apply equally to portable radio receivers,
radio telephones and instrumentation
equipment. At
the same time, the warld needs
a more efficient use of energy.
These conflicting demands force
designers of electronic components
to bring out ever faster,
smaller and moreenergy-friendly
devices. A logical consequence
of this is that res are becoming
smaller and smaller. This in turn
means that their dissipation becomes
a problem.
