Hans Camenzind

I design bipolar and CMOS Analog Integrated Circuits.  At the present time I cannot accept
new clients with major projects, but I will continue to devote part of my time to offering
help and advice in analog IC design and lectures on the history of electronics free of charge.

If you need suggestions for analog IC designs or help in solving a problem, please contact me.  This free service is intended for mostly for small companies who lack analog IC design expertise.  See also my book Designing Analog Chips, which you can download for free or purchase in printed form.

For a background on the lectures on the history of electricity and electronics see my book
Much Ado About Almost Nothing.  These 1½ hour presentations are intended for educational
institutions, corporations or gatherings of 30 or more people.

Hans Camenzind was born and raised in Switzerland and moved to the U.S. after college. He received an MSEE from Northeastern University and an MBA from the University of Santa Clara. After several years doing research in the Boston area, he moved to the West Coast to join Signetics (now Philips) and later started his own company, Interdesign. After heading it for seven years he sold Interdesign to Plessey. Since then he has been an independent design consultant in analog IC design. During his career he wrote three textbooks, designed the first integrated class D amplifier, introduced the phase-locked loop concept to ICs, invented the semicustom IC and created the 555 timer. He has designed 147 standard and custom ICs so far. Check out Camenzind's latest book on the history of electronics, Much Ado About Almost Nothing!
