Try searching for "multiple outputs flyback". Basically, you can't control each, individually, instead you make the voltage feedback as the average between the outputs. Here's a quick'n'dirty test ...
If you're referring to this Wikipedia page then the topology has a negative output. In that case, the problem as you have it stated in the OP, is misleading: it should be Vo=-20. With that, extract...
Yeah, that looks like it's going to be messy. I agree with Olin: the problem starts with three variables and three conditions so, no matter how you look at it, you will end up with a system of...
You can use various methods for it, one way would be to simply use the ideal transfer function and make it in parallel with $R_o$: $$\begin{align} A(s)&=R_{th}+\dfrac{1}{sC_{th}} \tag{1} \\ ...
Please note that the text refers to the integral, or the mathematical evaluation through integration which, indeed, cannot be obtained. But that doesn't mean you can't obtain the Laplace transfer f...
Around the 19 min mark in the video (approximately, found with hovering the cursor over the timeline) you'll see that different capacitors have different values of both capacitances and parasitics,...
I saw this link by accident and, while Andy's and Olin's answers are spot on, I thought I'd expand a bit on the complications they describe, just so you know what you're missing (or meeting, should...
I'm adding this as a corollary to Olin's post, in case an exact formula for attenuation is needed. That basic IIR is derived from the exponential moving average, and its impulse response is: $$h[n]...
R22, C22, C23, together with Rfbt (feedback top) and Rfbb (feedback bottom) form what is called a type II compensator, using TL431 as an opamp with built-in reference. The feedback network is a bit...
Your derivation is correct, you just missed the sign: $V_L=-V_C=2;\mathrm{V}$, because the capacitor charges with +2 V, and the discharge accounts for the negative sign on the inductor. The notatio...
It depends on whther the stages are buffered, or not. If they are buffered then it's more simple, because an RC lowpass has the transfer function: $$H_1(s)=\dfrac{\dfrac{1}{RC}}{s+\dfrac{1}{RC}}=\...
Unless you know the exact formula for the I-V curve, you will never find out anything analytically. Fair warning: very unlikely you will get such formula, since they are strongly non-linear in natu...
If you are pursuing engineering then you can't use doodles instead of schematics generated by dedicated (or not) programs. It will take you just the same amount of time, if not less, and the result...
Your requirements are odd. Can you specify what purpose that filter is for? I'm saying this because, for a -0.1 dB/Hz, a filter will have a continuously increasing attenuation slope. Think of it li...
This is mostly another view on @Olin's answer. For different input signals the frequency of the pole will have different values ,the pole as a pole exists for some specific values of L,C s but t...
You still haven't said why you need, or even what order, type, etc. Assuming it's a 2nd order, an exact solution involves creating a generic transfer function and then solving a system of equations...
