Study of Darlington Pair Amplifier with power supply Manufacturer,Supplier and Exporter in India

Product Code : SCL-EELE-12246

Indian Lab Suppliers supplies the Study of Darlington Pair Amplifier with power supply (Product ID: 12246) as part of its electronics engineering lab equipment range. It is a training board for comparing an emitter follower with a Darlington pair amplifier and showing the effect of bootstrapping.

Quick Answer

Students measure input impedance, output impedance, current gain and voltage gain for an emitter follower and for a Darlington pair, and compare the two sets of results. A bootstrapping experiment then shows how feeding the output back to the bias network raises the input impedance of the Darlington stage. The transistors are fitted on heat sinks, and a 24 V DC, 600 mA IC-regulated supply is connected internally. A decade audio generator, decade resistance box, digital AC voltmeter and 20 MHz oscilloscope are required.
