EXPLANATION OF THE PICTURES
- 1st picture is control to output transfer function. For thosewondering how I obtained this formula, you can checkControl to output transfer function.This formula was obtained with the help of VerbalKint.
- 2nd and 3rd pictures are my calculations about pole, dc gain, zeroand phase.
- 4th picture is ltspice simulation of this circuit.
QUESTIONS
I assume that the person who is going to try to answer the question knows the quadratic pole, zero and phase so ;
- As seen in my calculation, Q value is 1.033x10^-5, which is -99.71dB. Why does Q have such a strange value?
- I found the phase asymptote values for quadratic pole as 0 degreesand 10^48402, which is infinite. I cannot find the correct phasebreak points, where am I making a mistake?
- I found DC gain as 56 db, but I cannot see this value in ltspice, why?
- Quadratic pole phase also contributes -180 degrees, I cannot see this value in my own calculations or in ltspice?
- In general, although I retry my calculations many times, I always get strange values, where am I making a mistake? For this reason, I cannot see compatibility with ltspice.
