How do darlington transistors work?

A Darlington transistor it may contain one or more transistor in its case. the purpose is to amplify current by beta multiplication.


How can you implement darlington pair using mosfet?

its not too hard... darlington transistors are simply a pair of bipolar transistors which allow for control of a significantly greater current or voltage (or both) via a low power signal such as a microcontroller. Frequently Transistors that can control a larger current or voltage require a higher gate voltage (Vgs) to fully turn on the transistor than the microcontroller is able to deliver so a smaller transistor is used to boost the control signal. You can build your own darlington out of a pair of bipolars - one that runs at logic level and boosts the signal to control the second one that runs at the higher current & voltage of the end device. The same can be done with mosfets. There are a fair number of mosfets that can control a decent current and voltage but in many cases you'll need to use either discrete boost (charge pump) mosfets, or a control chip that has built in charge pump circuitry. This is a fairly common requirement in building motor controllers and amplifiers which are or can be controlled by PWM or some other form of logic level signal. The international rectifier IR2104 is a good example of logic level mosfet that can be paired with a more powerful mosfet such as IRF540N for the actual current control. As mentioned you can also use a driver circuit such as those found in the HIP408x series which will obviate the need for a boost mosfet - this configuration is found in a number of commercial motor controllers including those by numerous wheelchair manufacturers.

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.
