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). |

Operational Amplifier Noise - Techniques and Tips for Analyzing and Reducing Noise
Ovidiu Popa
 Ovidiu Popa reviews a book by Texas Instruments engineer Art Kay on the sources of opamp noise and how to minimize them. Although not an easy read for the beginner this book is delivering lots of engineering “rules of thumb”, which allows a quick and effective approach of circuit design, from a noise perspective. His verdict: if you have an operational amplifier noise problem to answer, Arthur Kay comes at the rescue: pick up the book and you’ll have your answer in the next ten minutes, in the good old tradition of American engineering literature.
