Step-by-step explanation of how voltage follower reaches steady state using negative feedback

Just one minute! I am not trying to understand what negative feedback does eventually, or why it should be used. I am trying to understand how the circuit reaches steady state, and how, step by step, the negative feedback causes Vout to be the same…

For below circuit, the simulation result is not matching with theoretical prediction

Please note that i1(t) is the loop current (in loop analysis method) and not the inductor current. The answer to above problem is option B, which is derived below Following principles are used: Capacitor acts as an open circuit under DC steady…

Is there a way to find the transfer function from only your input and the steady state response?

I know that a transfer function has the general form of $$ G(S) = Y(S)/U(S) $$ where \$Y(S)\$ is the output and \$U(S)\$ is the input. However, if given the output \$u(t)\$ and the steady state response \$y_{ss}(t)\$, is is still possible to obtain…

Calculating the impedance formula of an inductor

Assume we have a purely inductive circuit such as below: To calculate the most general case, \$V_1\$ is given as such: $$v(t) = V_m \cdot \cos(\omega t+\theta)$$ For an inductor, \$v(t) = L \dfrac{\mathrm{d}i(t)}{\mathrm{d}t}\$. Writing it in…

Nodal analysis on this sort of circuit

I'm reviewing nodal analysis on sinusoidal steady state circuits which my textbook typically only does mesh analysis on and I can't seem to get to the answer they obtained for an example problem. They obtain this after mesh analysis. My thought is…

Finding the K value for minimum damping coefficient

I have a block diagram, From the diagram, I think the two summing points at the middle of the diagram can be switched, therefore, I got open and close loop transfer function as below: $$ \begin{align*} L(s) & = \dfrac{K(s+2)}{s(s+1)} \\\ …

Extend classic transistor flip-flop to an n-state flip-flop?

There is the classic flip-flop using two transistors. I now tried to extend it to be able to store more than 2 states, and thought it'd be interesting to be able to extend it to 3 or an arbitrary number of states and came up with following…

Settling time from change in plant

I have an electrical circuit as shown below: I would like to formulate an equation for the settling time for the voltage on the capacitor node given a change in resistance on R2. I have calculated the transfer function to be $$ \frac{V_{cap}}{V_s}…

Laplace analysis of coupled circuit confusion

So i solved this by first finding differential equations and then by taking laplace transform of them here are my working- for left loop $$5i_{1}\left( t\right) +4.9\dfrac{d}{dt}i_{1}\left( t\right) -1.4\dfrac{d}{dt}i_{2}\left( t\right)=20\qquad…

Is it possible to change the reference clock in a cpu while it is running

I understand that PLLs have a settling time but if I were to do a hardware modification that changes Vco of a reference clock to scale based on temperature of my CPU, would I be able to do so while the CPU is running or would the system lock due to…

Is the frequency response of a circuit only valid for steady state (phasors)?

This is my first post. I just finished a course about advanced circuit analysis techniques (the content was taken from textbooks by Sadiku, Hayt and Irwin.) As you know, phasors are used to solve sinusoidal AC circuits (and also non-sinusoidal AC…

Steady State Error of Control System

I have a question regarding a control loop system which is subject to disturbance, unfortunately I missed a couple of lectures on the subject and now am scratching my head as to how to do it. The loop is shown below. \$D(s)=\frac{K}{s+10},\$…

Power absorbed by a resistor in a crossed circuit

The given problem above is asking for the power absorbed by the resistor R given R = 1 Ohm. According to my professor, the two inductors do not cross so I redrew the circuit into the one shown in the image below. I then redrew the circuit into its…
