- Derive the small signal equations associated with both the capacitor and inductor.
- Relevant Equations
- L dihat/dt=RHS
C dvhat/dt=RHS
I've attached my attempts at the solution and the actual question below. I believe the only issue I am having is I don't know how to get rid of "I" in both my final inductor and capacitor equations as the HW states I shouldn't have anything in term of I. I believe I need to put "I" in terms of the listed variables but I cannot for the life of me figure out how to do it. In the lectures and textbook that come with this HW they do actually leave the solution with terms that include "I" which is a bit frustrating. I already removed the second order and DC quantities as can be seen in the work but "I*Ron*dhat" and "dhat*I" are first order factors that should not be removed. The blue boxed in equations in third image are my incorrect answers for #1 and #2.
