| 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 2. 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. An individual device such as a 2N3904 etc. can be used for Q<sub>4</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 (when R<sub>2</sub> is 100Ω). | All the emitters can be tired to ground ( pins 3,7,10,13 ).
