[Solved] Comparing fixed and collector to base bias which of the following statement is true?

Q.	Comparing fixed and collector to base bias which of the following statement is true?
A.	fixed bias is more stable
B.	collector to base bias is more stable
C.	both are the same in terms of stability
D.	depends on the design
Answer» B. collector to base bias is more stable
Explanation: for fixed bias circuit, s = 1+beta, more the beta, lesser the stability for collector to base bias s = (1+beta)/(1+beta(rc/rc+rb))
