Cmos Vlsi Vtu Notes Cbcs

Vlsi design notes(1st unit) according to vtu syllabus.(BE) • 1. 1 VLSI Design UNIT -1 Introduction to MOS technology  Moore’s law  Speed- power performance  nMos fabrication  CMOS fabrication  n-well process  p-well process  BiCMOS  Comparison of bipolar and CMOS • 2 1 INTRODUCTION  Integrated circuit (IC):- an IC is a combination of interconnection circuit elements on a continuous substrate.  Substrate:- substrate is a supporting material upon which an IC is fabricated.  Wafer:- a wafer is a basic physical unit used in processing.

CMOS VLSI Design M.Tech. First semester VTU Introduction The present chapter first develops the fundamental physical characteristics of the MOS transistor, in which the electrical currents and voltages are the most important quantities. The link between physical design.

It usually contains large number of identical IC’s.  Transistor was invented in 1947.  The very first IC emerged at the beginning of 1960.
