As Wikipedia, the free encyclopedia, will explain,
Bipolar junction
transistors (BJT) are not only doped sandwiches, but also something
essentially contrary to CMOS. If we could only successfully apply the same
advanced processes used in CMOS manufacture today, to bipolar chips, we would
make a quantum leap forward to chips with absolutely undreamed-of levels of
performance. This CMOS gates demonstration will take your understanding of
CMOS
to the next level.
