### Finding transfer function of a compensator circuit similar to a type 2 compensator topology

I know how to find transfer functions of op-amp circuits using equations derived from using Kirchhoff's current law (nodal analysis), and normally I don't have any problems solving them. However, I ...

### Opamp: determine the transfer function with negative RC feedback

I would like to find the transfer function of the above ideal opamp circuit. One of my approach was neglecting the effect of R2(assuming the voltages on the both side of R2 are the same) and applying ...

### AC measurement in a circuit

I used the spice language to build an integrator op-amp, and one of the questions I had to address is to run an AC analysis on it. long story short- by looking at the transfer function of an ...

### Calculate transfer function of transconductance amplifier circuit

How can I model/calculate the behavior from Vin to Iout of the following circuit? (Credits of the picture go to Analog Devices): Essentially, I am interested in the large signal response, such as a ...

### Understanding in-loop compensation for capacitive-loaded OpAmp

I'm trying to understand the in-loop compensation for a simple amplifier loaded with a capacitive load, as seen in this article from Analog: http://www.analog.com/library/analogdialogue/archives/38-...

### Find transfer function of Op Amp system

Trying to determine the transfer function for this Op Amp circuit using the rules that $V-=V+$ and that no current flows into the Op amp. I think that $Vout=IR2$ and determined the trasnfer ...

### DC gain of non-inverting integrator / Derivation of DC results from transfer function

(The pictured circuit contains a serious mistake, see my answer for more detail. I decided to leave the question in its original form for educational purposes, though.) Setting The (sub-)circuit in ...

### How do I realize a transfer function with multiple zeros?

I designed a compensation function for a control system in Matlab and now I'm trying to figure out how to build it using op-amps. I thought I might be able to use a couple of Sallen-Key amplifier ...

### Simulating a tranfer function with opamps

I am asked to simulate the following transfer function using operational amplifiers: Obviously what it evokes is a second order filter, my question is what kind of filter should I use (Butterworth, ...
