 All the emitters can be tired to ground ( pins 3,7,10,13 ). Devices Q<​sub>​1</​sub>,​ Q<​sub>​2</​sub>​ and Q<​sub>​3</​sub>​ can be connected in parallel and serve as Q<​sub>​2</​sub>​ in figure 1. Q<​sub>​4</​sub>​ and Q<​sub>​5</​sub>​ can be used for Q<​sub>​1</​sub>​ and Q<​sub>​3</​sub>​ in figure 2. The 3 to 1 emitter area ratio will result in an output voltage very nearly 1.2 volts if R<​sub>​1</​sub>​ and R<​sub>​3</​sub>​ are both equal to 2KΩ. All the emitters can be tired to ground ( pins 3,7,10,13 ).
