The term Darlington transistor is named from its inventor’s name Sidney Darlington. The Darlington transistor is made up of two PNP or NPN BJTs by connecting together. The emitter of the PNP transistor is connected to the base of the other PNP transistor to create a sensitive transistor with high current gain used in many applications where switching or amplification is crucial. The transistor pair in the Darlington transistor can be formed with two separately connected BJTs. As we know that, the transistor is used as a switch as well as an amplifier, the BJT can be used to operate as an ON/OFF switch. Darlington Transistor...
