Well, i don't know, maybe yes or maybe not.1-Does Rin(base) mean R(th) ?
But which value for Ie your Professor will be preferred.2-In my study book,it shows me that if the following condition be ture,it will take the approximation.
"If βRE>>RTH, then IE=(VTH-VBE)/RE"
so, does my answer still be wrong?
first,thanks jegues and Jony130 very much for helping me !
I have some questions about Rin(base) in question 3.
1-Does Rin(base) mean R(th) ?
2-In my study book,it shows me that if the following condition be ture,it will take the approximation.
"If βRE>>RTH, then IE=(VTH-VBE)/RE"
so, does my answer still be wrong?
I'm not sure where your book is getting that, I would lean more towards my solution."If βRE>>RTH, then IE=(VTH-VBE)/RE"
so, does my answer still be wrong?
Maybe I'm pick on but if you looking into the base.Rin(base) means the input resistance looking into the base.
I believe it turns out to be what you have called Rth.
Hmmm... I'm not sure what you would call it then, but I'm fairly sure the intention was for it to be R1//R2.Maybe I'm pick on but if you looking into the base.
Then for sure you will see R1||R2 + (β+1)Re.
Are you sure you don't mean ....??Maybe I'm pick on but if you looking into the base.
Then for sure you will see R1||R2 + (β+1)Re.
Yes, my mistake.Are you sure you don't mean ....??
R1||R2||(β+1)Re
