Darlington Pair Amplifier Circuit Diagram. The first transistor s emitter is directly connected across the base of other transistor also the collector of the two transistors are connected together. Above figure shows a class a amplifier circuit that uses a darlington transistor configuration to have a high collector current.
Darlington transistor offers a gain that equal to the product of two individual gains. Above figure shows a class a amplifier circuit that uses a darlington transistor configuration to have a high collector current. Darlington transistor pair based rain alarm.
These are the mostly used ones with a number of applications.
The rain alarm circuit is built with the following active components such as sensor using two screws fitted over a plastic strip darlington transistor pair piezo buzz 9v battery 0 22uf 10k resistor. Therefore with a small base current the output current at the collector terminal is very high. In the below images two type of darlington transistor are shown. Darlington transistor offers a gain that equal to the product of two individual gains.
