VERY LARGE SCALE INTEGRATION

VERY LARGE SCALE INTEGRATION

ABSTRACT:

Electronics as we know it today is characterized by reliability, low power dissipation ,extremely low weight and volume, and low cost, coupled with an ability to cope easily with a high degree of sophistication and complexity .

Electronics , and in particular the integrated circuit ,has made possible the design of powerful and flexible processors which provide highly intelligent and adaptable devices for the user . Integrated circuit memories have provided the essential elements to complete this processors and together with a wide range of logic and analog integrated circuitry.

The invention of transistor by William B Shockley ,Walter H. Brattian and John Bardeen of bell telephone laboratories was followed by the development of the integrated circuits.

Over the past several years ,silicon CMOS technology has become the dominate fabrication process for relatively high performance and cost effective VLSI circuits.

VLSI technology providing the user with a new and more complex range of ’off the shelf ’circuits, but VLSI design processes are such that system designer can readily design their own special circuits of considerable complexity . This provides a new degree of freedom for designer and it is probable that some very significant advances will result .
