Can anyone help me with the question below? Not sure if this is a shunt-shunt circuit or something else.

 

What strategy or rules were you taught for identifying the feedback topology?

I don't remember correctly, as it was a little while ago and I am retaking the class again. Are you able to tell what circuit it is?

The circuit in the question seems like a voltage series, am I correct?

What does a Voltage series amplifier translate to, as we never used that term in class or the book. We only used, series-series,series-shunt, shunt-series and shunt shunt.

Would appreciate the help

 

Also can anyone help me identify which part is the feedback network, and how to find out the feedback coefficient with the values given in the question

No this is not voltage series. This circuit could be voltage-series if Vout was at Q2 emitter but he isn't. What about current-shunt ( shunt-series )?

Yeah that makes more sense. How would you find the feedback factor/coefficient for this?

Edit: Nvm just saw the post

My circuit doesn't have an Rf so how would I calculate the feedback factor?

 

What about 20K connected between Q1 base and Q2 emitter ??
