Op-Amp Circuit Stability Although op-amps behave as single-pole amplifiers which are "unconditionally stable," it's still possible to make unstable amplifiers if you don't know what you're doing. The most famous example of this is the voltage differentiator 1. Consider the following circuit: a. Find the expression for this amplifier's ideal gain Aco (s), assuming the op-amp is ideal (a(s) - o. Hint: It's just an inverting amplifier with z and z2 R (5pts) b. Suppose the gain-setting components have values...
