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 ...

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

There is no loss in the system, therefore the startup transient continues oscillating forever. (Due to numerical errors in the transient simulator, it won't actually go forever.) The measurement is ...
