- Homework Statement
- All the BJTs are the same, prove Vref = 2Vbe
- Relevant Equations
- KVL, ohms law, BJT properties
I am given that all the BJTs are the same.
First of all, when finding node voltages like Vref should I make the node voltage a voltage source first and then do circuit analysis? If so then I would use KVL but that does not give me Vref = 2Vbe.
I do know that Vref = Vb1 = Vb2. What am I doing wrong here? How would you find Vref?
