Popa Ovidiu

Ovidiu Popa was born in 1958 in Bucharest, Romania. After a long and rewarding career in academia (including a PhD in EE), and R&D in the semiconductor industry with a special focus on semiconductor devices and materials characterization and mathematical modeling, he moved in the early 90’s towards the IT industry. After IT contracting across the world for almost a decade, he is today Software Engineering Manager for a major Canadian telecom operator.

 

Audio was his hobby from the pre-teen age, building his first tube (6N1P + 6P13S) amp at the age of 13 and the first class AB, OC26 germanium quasi-complementary, solid state amp at the age of 14. Ovidiu is currently running his hobby audio lab in the basement of his Toronto suburb home. His current audio interests are low noise designs, high power linear audio amps and negative feedback theory and applications for audio. As a second hobby, he enjoys music (mostly progressive and alternative rock) and movies (of his ever growing collection of over 400 DVDs).
