Just Use A 100Ω Resistor

摘要

So there I was, a new hire for a leading-edge analog-electron-ics company. As it was my first job, I was wide-eyed and excited-confronting new problems left and right. One problem I ran into involved the stability of an amplifier circuit. In this application, a buffer-amplifier circuit, with a capacitive load, sang like a bird. Because I had a huge community of experts around me, I ran around and asked for advice. Thernwords or wisdom that came down tornme were, "Oh, put a 100ft load resis-rntor between the amplifier output andrnthe load capacitor." When I askedrnwhy, the engineer said, "Just do it.rnTrust me; it will work."
