5. GH(s) is a minimum-phase system which has the Bode plot shown below. It is desired to increase the phase margin by 40 degrees and also increase the closed-loop system bandwidth. Design a lead compensator for this purpose. Determine (1) the ratio of the pole to the zero, α , (2) the frequency where the maximum phase shift from the compensator should be placed, and then (3) the pole and zero. You need not draw the Bode...

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...
