Lecture 1-Introduction PDF

This document provides an overview of the syllabus for the course EC8453 LINEAR INTEGRATED CIRCUITS. It discusses the basics of operational amplifiers and integrated circuits. An integrated circuit is defined as a miniature, low cost electronic circuit consisting of active and passive components fabricated on a single crystal of silicon. The document outlines the evolution of electronic devices from vacuum tubes to modern integrated circuits and discusses some of the pioneers in integrated circuit development like Jack Kilby, Robert Noyce, and their contributions. It also lists advantages of integrated circuits such as miniaturization, cost reduction, increased reliability, and performance.

INTEGRATED CIRCUITS

miniature ,
low cost electronic circuit
consisting of active and passive components
that are irreparably joined together on a single crystal of silicon.
An integrated circuit (IC) is a miniature ,low cost electronic circuit
consisting of active and passive components fabricated together on a
single crystal of silicon. The active components are transistors and
diodes and passive components are resistors and capacitors.

subsequent development of the microelectronics have done more
to shape the modern era than any other invention.

Jack St. Clair Kilby
 Born in 1923 in Jefferson City, MO
 EE degree from University of Illinois in 1947
 He invented the integrated circuit in 1958 while working at Texas
Instruments.
 In 1970, in a White House ceremony, he received the National Medal
of Science.
 In 1982, he was inducted into the National Inventors Hall of Fame.
 He was awarded the Nobel Prize in Physics in 2000 for his
breakthrough discovery.
TI’s First IC
Robert Noyce
 Born in 1927 in Grinnell, IA
 Ph.D. from Massachusetts Institute of Technology in 1953.
 Worked for Shockley Semiconductor Labs in CA
 Co-founded Fairchild Semiconductor in 1957 and
Intel in 1968.
 Intel's headquarters building, the Robert Noyce Building, in Santa Clara,
California is named in his honor.
 Nicknamed the “Mayor of Silicon Valley”
 Improved upon Jack Kilby’s IC (microchip)
 Fabricated chip with entire components out of a single piece of silicon –
almost like a sculpture
 - the planar IC, which got help from Swiss Fairchild employee Jean Hoerni
The first Planar IC – Fairchild

Advantages of integrated circuits
1. Miniaturization and hence increased equipment density.
2. Cost reduction due to batch processing.
3. Increased system reliability due to the elimination of
soldered joints.
4. Improved functional performance.
5. Matched devices.
6. Increased operating speeds.
7. Reduction in power consumption

IC Classification
Based on the signal treatment
 Digital ICs-Logic gates, Counters, digital clock, etc
 Analog ICs- Op-amps, Voltage regulators, timer
 Mixed ICs- combination of both analog and digital signal
processing
