feedback is a awful thing?

Do you think so?

How to calculate it by hand?

I read Razavi, but I don't think it descripts clearly!

I read Allen, but I didn't mention it.

I read Gray, but I still think it descripts too simple.

Any other material?

Chinese ones maybe perfect.
 

it depends. feedback is like a nuclear reaction. if its well controlled you can use it for something useful like generating energy. simillarly feedback can be used to create an oscillator. an oscillator is a very important circuit building block. infact an oscillator is as important as a power source for circuits.

and if you have an uncontrolled nuclear reaction it could become a nuclear bomb. simillarly uncontrolled feedback can destroy the purpose of a circuit.

can you be a little specific. are you studying a circuit or some article? a schematic or some reference might be helpful
 

The governor on a steam engine is feedback, the faster the engine runs, the centrafugal force throws out those balls, and the engine is controlled and hits a steady speed. I wonder how that would look descibed in calculus? Unless you are studying to pass an exam, don't worry about it to much.
Modern circuit design is like Leggo, just stick the ready made blocks together!
 

Just a word of caution - if you adopt that atitude you are very likely to end up in disaster. Well, this in case you care about it.
 

yes it is... ...in power electronics (switching devices), or other analog critical circuits it is a serious problem...

... ofcourse it can be solved in some way .... :wink:
