Mike M comments:
Bob has a vast knowledge of analog circuit design gained from many years of experience. He also has a practical working knowledge of digital circuits that compliments his analog capabilities. Bob readily offers excellent advice and suggestions. I have been able to take advantage of this numerous times while addressing my own design tasks. Example topics include DC-DC converter isolated feedback techniques, quick-turn dissipation estimates for power transformers based on simulation, discrete differential amplifier implementation, butterworth filter implementation in complex power circuits, and ferrite switch dissipation modeling.
