From my understanding, the root locus is only concerned with open loop gain. I figured this means you would ignore the negative feedback loop and calculate the root locus from just the plant's function
Workings:
zeros: -1
poles: 0, -2, -2,
relative degree = 2
=> 90-degree asymptotes

2. Homework Equations
Adiff(single-ended)= 1/2gm*ro||Rd
β=R2/(R1+R2)
3. The Attempt at a Solution
I am really confused as to how to find A. I know the feedback of the circuits around the R2 and R1, but I dont understand how the open loop gain can be found. Can...
1. Homework Statement
By Wien bridge oscillator (abbreviated as WBO below) I refer to this circuit where the op-amp is assumed to be ideal and the output is the voltage drained from the upper end of R3.
What confuses me is that I hardly find a reference which explicitly states that a WBO...
I´m taking a course on control engineering and I have a test next Tuesday so I need to study the basics which are: Laplace transform, simplification of block diagrams, and analysis of transient and steady state responses. Right now I am dealing with the second one.
I know the basic rules of...
