Impact of Input Capacitor on the Derivation of the Small-Signal Model of the Buck-Boost Converter
Most of the small-signal analyses consider a perfect input source so that the voltage biasing the converter is constant and equal to zero volt in ac analysis. In reality, the source features an output ...

Impact of Input Capacitor on the Derivation of the Small-Signal Model of the Buck-Boost Converter
If your model has the supply as a voltage source the addition of the capacitor does nothing. if you model is more realistic, the capacitor makes the supply more like a voltage source.

Small signal analysis confusion: which zero load condition should I use?
The circuit you are showing is not a current mirror, but a common gate stage with a current source load. The current source load is a current mirror, but the input of the circuit is the source of Q1 ...

Small signal analysis confusion: which zero load condition should I use?
Zero load, defined in our class, is when Iout=0 or Vout=0
You may be misinterpreting it. Zero load with a resistive load is when Vout=0. But that's the only case when Vout=0 means no load: it's 0V ...

Why does parasitic capacitor have no effect on the output side of amp?
Most likely because the miller cap appears at the output with \$\frac{A+1}{A}\$ gain factor, which is very close to 1 if \$A \gg 1\$, and many times \$C_\mu\$ is smaller than \$C_\pi\$.
I derived this ...

Is it possible to find bandwidth without r0 in small signal hybrid-π BJT?
Some time ago I did a complete study of the bjt ce, I think it might interest you, you can find it here: https://i.sstatic.net/JHXd6n2C.png (you have to zoom), (Sorry, the chosen bjt is the 2N4400 and ...

I designed an Op Amp but the feedback loop would not generate the expected behavior
The input stage isn't really differential, you have the collectors connected together when they should be separate.
The simplest way is to have a resistor between each collector and the associated ...
