VLSI?


ICs are the basic block of electronic device design.


They contain many transistors on one chip.


Digital devices rely on digital logic.

Conclusion


VLSI is a mature field of electrical and computer
engineering that deals with semi
-
conductor
properties to design patterns that form the building
blocks to serve digital circuit design purposes.


BiCMOS
, ECL, TTL technologies currently used. Each
has its own applications for
its advantages.


Serious VLSI research, design and cutting
-
edge
manufacturing takes place in extremely
sophisticated factories and labs (
fabs
).
