Bypass Capacitors… yes, but why?

Good stuff! Another suggestion for a future article: what type of capacitor to use for this purpose.

Great idea, Walter. Good grounding and bypassing is a tough topic for a short blog. I'll try to condense it to its essence in a future blog. -- Bruce

Thanks, Bruce. Perhaps in another article you could enlarge a bit on the question of where the "other end" of the bypass caps should go? We all know that the caps should be close to the supply pins, but at the other end, are we trying to minimize impedance to the ground point of the load, or to the power supply, or what? How can we prevent the distorted current signal that is traveling through the bypass cap from inadvertently imposing a voltage on, e.g., the inverting input? And what are the rules for single-supply opamps?

Great article Burce. As always, I welcome your insight with great delight.
