Last time we looked at configuring an op-amp with negative feedback, but with enough reactive (phase shifting) components to make it unstable. The trouble with the amplifier of choice is that it’s a very low-bandwidth part, intended for use amplifying slow or nearly DC signals. The size of components required […]

Cooking with Op-Amps, part 7: Test it!

Last time around we explored setting gain in inverting and non-inverting configurations, and how phase affects performance. This time, we embrace failure, in theory. We learn more when things go wrong, and an unstable amplifier could be classed as having gone wrong. Instead of waiting like lambs for the (ahem) […]
