Call the office for discounts on enrolling in multiple Doug Smith courses; this course, Failure Analysis and ESD: Design and Troubleshooting, 781-245-5405

This course covers techniques applicable to design and verification of high-speed digital and analog circuits.

About the Course

The course delivers practical knowledge for SI design troubleshooting and verification that can be used immediately on the job. The course material contains design tips and troubleshooting techniques developed by Mr Smith, many of which are unpublished and have solved engineering problems in less than a day that were not solved by published methods with weeks or months of effort. Electronic engineers from all fields will find this course useful.

This seminar describes in depth how to measure signal and noise in high speed digital and analog circuits. These measurements are then used to characterize high speed effects in electronic circuits including design verification and troubleshooting. Sources of measurement error are discussed. The measurement techniques are related to design issues to improve signal integrity, equipment EMC performance, and improve the overall reliability of electronic systems.

Emphasis is placed on delivering practical knowledge to SI and circuit designers that can be used immediately on the job. Some class time is reserved to discuss problems and interests of those attending. Each seminar delivery is modified to fit the interests of the attending students.

Instructional Methods

The course includes a combination of teaching methods including lecture, live experiments, live computer simulations, still pictures of experiments with results, and video. The combination of methods combined with Mr. Smith’s enthusiastic presentation style helps the students learn and enjoy the course.

Who is it for?

All circuit designers (especially those involved with signal integrity issues), design supervisors, and manufacturing test engineers.

Prerequisites

A college-level course on circuit analysis is desirable although the seminar will be useful to those with two-year technical degrees.

Benefits

Course Presenter

Douglas Smith, Author of High Frequency Measurements and Noise in Electronic Circuits

Mr. Smith held an FCC First Class Radiotelephone license by age 16 and a General Class amateur radio license at age 12. He received a B.E.E.E. degree from Vanderbilt University in 1969 and an M.S.E.E. degree from the California Institute of Technology in 1970. In 1970, he joined AT&T Bell Laboratories as a Member of Technical Staff. He retired in 1996 as a Distinguished Member of Technical Staff. From February 1996 to April 2000 he was Manager of EMC Development and Test at Auspex Systems in Santa Clara, CA. Mr. Smith currently is an independent consultant specializing in high frequency measurements, circuit/system design and verification, switching power supply noise and specifications, EMC, and immunity to transient noise. He is a Senior Member of the IEEE and a former member of the IEEE EMC Society Board of Directors.

His technical interests include high frequency effects in electronic circuits, including topics such as Electromagnetic Compatibility (EMC), Electrostatic Discharge (ESD), Electrical Fast Transients (EFT), and other forms of pulsed electromagnetic interference. He also has been involved with FCC Part 68 testing and design, telephone system analog and digital design, IC design, and computer simulation of circuits. He has been granted over 15 patents, several on measurement apparatus.

Mr Smith has lectured at Oxford University, Vanderbilt University, University of California, Berkeley,  AT&T Bell Labs, and at many public and private seminars on high frequency measurements, circuit design, ESD, and EMC. He is author of the book High Frequency Measurements and Noise in Electronic Circuits. His very popular website, www.emcesd.com www.dsmith.org, draws many thousands of visitors each month to see over 60 technical articles as well as other features.

“Excellent demonstrations, much easier to understand than lots of equations” Tony Shaw, Principal Engineer, Sony Semiconductors Additional comments from people recently taking the course One of the best classes I’ve ever attended. Very practical information that can be easily applied to all designs. Great!! Very useful!!· I appreciate the practical examples and “war stories” The book of slides was very effective. The industry contacts and tool suppliers was good, too.
