Mastering Equations in Electronic Circuits-1: Tips and Tricks

[praveena]

I become confused & feeling hard to study equations in electronic circuits-1 subject.
i am feeling very difficult to derive equations in this subject. I feel there is no practical knowledge in this subject.can anyone suggest me to study this subject in easy way? I have tried my best for a good understand study? Yet it failed!

What kind of equations/problems are you finding difficult? specific examples would help.

 

[praveena]

Questions like: deriving equations for * Fixed bias circuit.
* Voltage divider bias
* Bias & Diode compensation
* Filters
* Thermal stability
* Biasing JFET
* Biasing MOSFET
* Multistage & Differential amplifier
* Small signal analysis of JFET
Thanks in advance

Are you looking for something like this?

They use Kirchoff's laws to get the equations.

yeah I know that they were using kirchhoffs laws. But they are inserting some equation which is not related? and these equations are some times came from someother calculations. but i will thank you for your help.

 

[jedishrfu]

Give us an example that goes beyond Kirchoff's laws and maybe another member here will be better able to help you.

While deriving stability factor S,S',S" for voltage divide bias. Can you derive me the equation for the given three stability factors?
