The Darlington Transistor named after its inventor, Sidney Darlington, is a special arrangement of two standard NPN or PNP bipolar junction transistors (BJT) connected together as shown below. The Emitter of one transistor is connected to the Base of the other to produce a more sensitive transistor with a much larger current gain being useful in applications where current amplification or switching is required. Connect two NPN transistors to form a Darlington pair and plot the Gummel characteristics. Show that B at any Vag is multiplication of ßs of the individual transistors. Colector Base O- TR: TR: NPN Emitter
