I think “change” will come to define the year of 2015 for me.

After 16 years in the Greater Seattle Area, I moved to Calgary, Canada in September of 2015. Having lived my entire life at sea level in a maritime temperate climate, I now find myself in a continental climate at an elevation of 1050 meters, admittedly, with some trepidation about what the winter will bring.

I decided to leave my job with Texas Instruments (formerly: National Semiconductor), where I’ve worked for decade, to further pursue other passions. One of these passions is high-performance audio circuit design. I am now relying on Neurochrome as my sole source of income while I pursue a second career, following another passion, in psychology. I am presently a full-time student at the University of Calgary.

My interest in electronics started in the early 1980ies when I started building power supplies to power various experiments, usually involving letting the magic smoke out of electronic components. My career in electronics started in 1991, while I was still in high school, when I landed a job as an electronics technician. In 2002, I earned my Master’s degree in Electrical Engineering at University of Washington, Seattle. My electronics career continued at National Semiconductor and Texas Instruments where I designed precision op-amps and precision timing circuits for use in cellphone base stations.

Another interest of mine is leadership and organizational behavior. Sadly, these areas tend to be under-prioritized at many companies, as they are not guaranteed to provide revenue growth next fiscal quarter but are rather more likely to provide a long-term benefit. It is, however, interesting to note that many software companies are ‘getting it’. And as a result, they are reaping the long-term benefits in form of lower employee turnover, higher employee satisfaction, fewer sick days, and, ultimately, a stronger bottom line. I tend to approach leadership from a psychological point of view with focus on communication, human interaction, and transactional analysis.


Design Philosophy

My philosophy is simple: Engineering : : Done : : Right.

I set my customers and clients up for success. I provide well-designed circuits and circuit boards that are well tested, peer reviewed, and well documented. My boards have all been prototyped before production and the bugs have been ironed out. The board layout does matter for circuit performance. If you want precision performance – i.e. low susceptibility to electromagnetic interference and low noise – the board needs to be optimized for signal integrity. This is especially important in circuits that require high signal-to-noise ratio, such as audio circuits, and in circuits that is exposed to fast current spikes, such as high voltage regulators and switching regulators.

All circuits and circuit boards offered on this page are peer reviewed and have been optimized for signal integrity and circuit performance. In addition, all audio circuits have been extensively tested by listening tests.
