Definition of small-signal capacitances calculated by Sentaurus TCAD Mixed-Mode/AC Analysis
I'm currently working on a capacitance model which will be part of a greater compact model for a planar RFET.
I use Sentaurus TCAD to generate capacitance data, which I use to understand the ...

Is the "\$\small o\$" in \$r_o\$ short for output or number 0?
You usually see ro in the small-signal models of BJTs or MOSFETs like this.
I'm curious if the "o" there is short for "output" or just the number zero? I think I saw people reading ...

Flyback converter small-signal model
I am currently designing a flyback converter and I am interested in measuring the stability of the converter (with a Bode plot). I will try to connect an isolation transformer on the feedback loop ...

Cannot obtain a generalized state space averaged model for simple wireless power transfer system
this is the first time I ask a question. I am currently working on finding a state space model of the following system :
where \$U_i\$ is a square wave of amplitude \$U_{in}\$.
This circuit ...

Modelling Biased APD In Integrator Circuit
I want to model a biased APD (Avalanche Photodiode) whose current output feeds into an integrator. For the IC I will be using, TI recommends the following configuration for an unbiased photodiode.

What is the difference between large signal model/analysis and dc model/analysis? [closed]
I am studying microelectronics. I have studied about the DC analysis and the AC analysis. The DC analysis is just to find the operating point or the quiescent point and then the AC analysis is done. ...

Is the hybrid-pi parameter hie really equivalent to (beta+1)*re?
I'm reading a book on feedback amplifiers at the moment and it makes comprehensive use of a simplified hybrid-pi model. A parameter that keeps popping up is hie and I've always considered this to be ...
