BIPOLAR JUNCTION
TRANSISTOR (BJT)
,Introduction
In 1904, the vacuum tube diode was introduced
by J.A. Fleming.
In 1906, Dr. Lee de Forest added a third element
called the control grid
On December 23, 1947, the first transistor was
demonstrated by Walter Brattain and John
Bardeen, together with William Shockley, at the
Bell Telephone Laboratories.
, Introduction
The first transistor was
called point-contact
transistor.
The term “transistor” was
given by John Robinson
Pierce.
