### Determining the zeros and poles of a common emitter amplifier

I have gone through the derivation of the transfer function of this transistor-based amplifier, including the dc-block capacitors and the two parasitic contributors. Needless to say that without the ...

### Disturbance error transfer function

Here is where you went wrong : Here is what i found out: \\$ Y = \frac{A}{s(\tau \cdot s + 1)} [-Y \cdot h \cdot k_p + \frac{B}{A} \cdot W] \iff T(1+\frac{A h k_p}{s(\tau s +1)}) = \frac{B}{s(\tau s +...

### Solving complex opamp circuits

I've grabbed up the part you seem to be asking about and labeled an additional node. I'll be using SageMath/SymPy for the symbolic KCL analysis. It flows about like this: ...

### Solving complex opamp circuits

It's called an MFB band-pass filter and is well-known in the industry. Here are a few references that get you started on what it's all about. Ref 1 from ESP Ref 2 from MT-218 Ref 3 from eCircuit I'm ...

### How can these passive RLC circuits change a sinusoid's frequency?

How can these passive RLC circuits change a sinusoid's frequency? There is no change. Only the "true" response to a "step sinusoid" of an infinite Q of a circuit. And how do I ...
