Notes from Lecture 1: Digital IC Design

Introduction

  • The course covers all topics related to Digital IC Design.
  • Some may prefer specific topics while others want a comprehensive overview.
  • The first lectures will focus on the introduction to integrated circuits.

Historical Context

  • Image of ENIAC (Electronic Numerical Integrator and Computer) used to illustrate the evolution of computing.
  • Early computers used vacuum tubes and consumed 150 kilowatts of power.
  • Significant advancements in electronics over the last 70 years have permeated all engineering fields.

Key Concepts

Transistor Introduction

  • The invention of the transistor was crucial for electronics development.
  • Early transistors were large (on the order of micrometers), now shrunk to nanometers.
  • Scaling down transistor sizes increases their speed and number per silicon area.

Integrated Circuits (ICs)

  • The first integrated circuit was created in 1958, leading to modern processors containing billions of transistors.
  • The relationship between transistor size reduction and increased integration density is emphasized.
  • Example of an accelerometer as an application of IC technology in smartphones and automobiles.

Market Overview

  • Rapid growth in the semiconductor market, expected to reach $500 billion in 2019.
  • Information and Communication Technology (ICT) market is even larger, facilitating further opportunities.

Key Events

  • Significance of the Space Race, leading to the creation of NASA and DARPA, which funded innovations in the semiconductor industry.
  • The establishment of the National Technology Roadmap for Semiconductors (NTRS) in 1992 for planning future semiconductor developments.

Moore's Law

  • Mooreโ€™s Law highlights the exponential growth in transistor density and performance.
  • Challenges arise not only from physical limits but also from increasing fabrication costs.
