The genesis of low power electronics can be traced to the invention of the bipolar
transistor in 1947. Elimination of the suppressive requirements for several watts of
fi lament power and several hundred volts of anode voltage in vacuum tubes in exchange
for transistor operation in the tens of milliwatts range was a breakthrough of unmatched
importance in low power electronics. The capability to fully exploit the superb ...
