If the reference and collector current are 0.539mA and 0.49mA respectively, how many transistors are used in current repeater circuit? (Assume β =150)

If the reference and collector current are 0.539mA and 0.49mA respectively, how many transistors are used in current repeater circuit? (Assume β =150) Correct Answer 14

The current equation is given as IC= Iref×β/(β+1+N) ⇒ 0.49mA= 0.539mA×150/(150+1+N) ⇒ N=14.
