Thierauf Design & Consulting: Signal Integrity Design, Analysis & Training

I’ve been in industry for over 40 years, designing custom high-performance CMOS memory and on-die I/O circuits (including SerDes) at the transistor level and using SPICE and numerical tools such as Matlab® and Octave to develop the signal and power integrity rules for many dense, high performance circuit boards and backplanes. I spent a year researching lossy transmission lines as a Visiting Scholar at Northeastern University in Boston.

Debugging the custom IC’s at the transistor level and boards at the signal level has given me insight into how IC’s and circuit boards interact, and has taught me many practical lessons regarding signal and power integrity. Along the way I’ve become proficient in using oscilloscopes, comm analyzers, TDR's, BERT testers and RF test equipment including VNA's, spectrum analyzers, and antenna analyzers.

Since 2011 I’ve been in private practice where I’ve helped my clients solve vexing signal and power integrity problems. I particularly enjoy working with small firms, including startups, but I’m no longer accepting new clients.

I’ve authored four signal integrity books, wrote the I/O design portion of the chapter that appears in, "Design of High-Performance Microprocessor Circuits", and co-authored 5 journal articles regarding microprocessor design.
