The Transistor
The invention that changed the world
and
One of It’s Inventors, William Schockley
Transistors can be used
For amplification or as
a switching circuit. They
were developed as a
replacement for the
Vacuum Tube
The First Silicon Transistor produced
by Texas Instruments in 1954
As an amplifier, the
Transistor can boost
a small signal to very
large signal.
The switching Transistor is
At the heart of many modern
Electronic circuits including
The computer
As a switch, the
Transistor can be used
to manipulate the 1’s
and 0’s used in
computers
Simple circuit for a Transistor.
Modern Transistors
Three Transistors on a single chip. One of the first integrated
circuits used in the IBM 360 Computer in 1964. An integrated
circuit this size can now hold millions of transistors.
William Shockley
Shockley co-invented the first transistor .
He was awarded the Nobel Prize for
Physics in 1956. His research explained
exactly how a Transistor worked at the
molecular level.
Shockley is credited for giving birth to
the “Silicon Valley” area in California.
Shockley was also a avid mountaineer
and pioneered several new climbing
Routes in the “Gunk's”.
Bill Shockley and Charles Kittel climbing in
the Watchung Reservation in New Jersey.
