I have been designing mostly high voltage power supplies for Travelling Wave Tubes and Cathode Ray Tubes for a long time. On occasion, I have also designed low voltage supplies. I also designed microwave amplifiers using these TWTs for a variety of applications, such as satellite communications, RADAR and Electronic Counter Measures. Sometimes these systems get fairly complicated and I started using microcprocessors in HV supplies to help with control and monitoring in the late 1980's, which was considered by many to be a stupid idea at the time. How times change!
Of course, the march of microcontrollers has not stopped since and they are now pervasive. Just a week ago I used a small Silabs 8051 uC to generate a stable 80kHz clock because it required fewer components and was smaller than a 555.
I started my career in France in the late 1970's and I moved to the USA in 1985. If you read my comments, you may spot the occasional French word!
I consider myself more of an analog guy gone astray with software, but I think that significant exposure to both worlds has served me and my customers well. My analog experience gives me a solid skepticism of the infallibility of digital systems, yet it is obvious that digital systems have allowed precision analog to shine for what it is best for.
I always welcome a healthy debate about the relative merits of both, and how to approach the difference in a way that improves the end product.
Born and raised in what was then Rhodesia (now Zimbabwe), Aubrey Kagan completed his electrical engineering degree at the Technion, Israel Institute of Technology, and obtained an MBA at the University of the Witwatersrand in South Africa. He immediately started working in electronics and was fortunate enough to be around as microprocessors made their first inroads into industry. He was initially involved with designing controllers for industry and mines, with projects encompassing coffee packaging machines, railroad communication controllers, hydrological data monitors, automatic calorimeters, and diamond sorters. The isolation of South Africa (geographically, economically, and later politically) allowed him to gain a wide range of experiences with many aspects of the industry, including analog and digital circuit design, the use of PCs (including the use of spreadsheets) to gather data, and the early use of CAD.
Aubrey now lives in Canada. Here he originally worked on the specifications for the Canadarm 2 (the remote control arm on the International Space Station), but he is now involved with far less grandiose projects. He is Engineering Manager at Emphatec, a Toronto-based design house of industrial control interfaces, signal conditioners, and switch-mode power supplies. Aside from brief forays into the i80960, i8096, and IM6100, all of his experience has been on 8-bit micros – including Intel (8048, 8051, 8080, 8085), RCA (1802), Zilog (Z80, Z8), PIC (16Cxxx), Scenix (SX18), TI (TMS7000, MSP430 – 16 bits!), and Cypress (PSoC). His specialty lies in blending the linear with the digital hardware and then processing in software.
Aubrey has written several technical articles for Circuit Cellar and has contributed several design ideas to EDN and Electronic Design as well as an application note for Cypress Microsystems. He has also made a few contributions to Max Maxfield's "How It Was" series and Max/Brian Bailey's "Travel Nightmare" series. He is the author of Excel by Example: A Microsoft Excel Cookbook for Electronics Engineers.
