Why darlington pair is also known as superbeta transistor?
I also don't know..plz....help me...
Does a transistor switch circuit with a darling ton pair have two switching thresholds?
Yes, a transistor switch circuit using a Darlington pair can exhibit two switching thresholds due to the characteristics of the two transistors involved. The first threshold is related to the base-emitter voltage of the first transistor, while the second threshold is influenced by the combined voltage drop across both transistors when they are in the on state. This behavior can lead to a more complex input-output relationship compared to a single transistor switch.
What name is aplied to the two types of BJT transistor?
PNP and NPN. The NPN is easiest to manufacture and implement. Not really a third type is the Darlington Pair, but students tend to blush when they talk about it. It has a higher gain and is contructed from two NPN's.
What is ULN2003 integrated circuit?
as a buffer circuit... means whenever u need a high current.... e.x-> if u wnat to run a 12V relay using a PC parallel port(DB-25) output, u kan use such a TTL IC.... if u just connect the relay it will never switch!! the current in a parallel port output will just be enough to light 2 series LEDs.... ULN**** ICs are used in circuits that use PIC ICs(micro controller)..... Also ULN**** series ICs has low power dissipation... -R-
What is the advantage of the darlington arrangement for the CC amplifier?
The Darlington arrangement in a common collector (CC) amplifier provides high current gain while maintaining a relatively low input impedance. This configuration consists of two bipolar junction transistors (BJTs) connected in such a way that the current amplified by the first transistor is further amplified by the second. This results in a significant increase in overall current gain without sacrificing the linearity or bandwidth of the amplifier. Additionally, the Darlington pair can drive heavier loads due to its ability to provide higher output current.
What is a Darlington transistor composed of?
The darlington configuration is two transistors connected in such a way that the gain (hFe) of the pair is higher than either transistor taken individually. The two collectors are connected together, and used as the collector of the pair. The base of the first transistor is the base of the pair. The emitter of the first transistor is connected to the base of the second transistor. The emitter of the second transistor is the emitter of the pair. Sometimes there is a resistor between the second base and the second emitter, so as to stabilize the pair in certain conditions. Typically, you multiply hFe's in darlington configuration, so if each transistor had an hFe of, say, 100, then the hFe of the pair would be 10,000.

What is darlington configuaration?
A Darlington pair uses two transistors connected to behave as a single transistor with a very high current gain (beta). Transistor-1 has its collector connected to the collector of transistor-2. Transistor-1 has its emitter connected to the base of transistor-2. The base of transistor-1 with the emitter and collector of transistor-2 is used as a single transistor.

Can you see transistors?
Basically, in transistor, the signal is transferred from low resistance circuit to the high resistance circuit. So it is called transfer+resistor=Transistor.Transistors are widely used in different types of switching, amplifiers, oscillators and integrated circuits.Based on the applications, the types of the transistors are as given below:General purpose transistors, Low frequency transistors, High frequency transistors, Power transistors, Switching transistors, Field Effect Transistors, MOSFET, Uni-junction Transistors, Bi junction transistors, Photo transistor, High power transistors, Complementary pair, Darlington amplifier, Video and R.F. amplifier, Ultrahigh frequency and microwave, Insulated gate bipolar transistors, Static induction transistors.More their to know about transistors are as given below:History of invention, Time-line throughout, Basic construction, Bias arrangement, working, Various currents in transistors, Basic transistor amplifier, Configurations, Characteristics, Current gain and relation among them, D.C. load line, Operating point, Biasing of transistor, stability factor, specifications and ratings, testing, colour coding, identification of transistor using multimeter, h-parameter of transistor, particular applications etc...
