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.
