Darlington pair applications
Weband collectors of the Darlington is the easiest way to emulate a constant current source (R6 in Fig. 1). Because the RF output of the Darlington Pair is also used for the DC bias, an RFchokeisrequired(L1)toconnectthevoltagesupplytothe output. RF coupling capacitors may also be required on the RF input and RF output because the input and output ...

WebSep 12, 2024 · Darlington Pairs Sometimes you want to control a really large amount of current; more than a single transistor's gain can provide. I.e. the output current has to be more than the input current multiplied by the transistor's gain. In this case we can combine two transistors in what is called a Darlingtion connection. WebOne advantage over the Darlington pair is that the base turn-on voltage is only about 0.6 V, or about half of the Darlington's 1.2 V nominal turn-on voltage. Like the Darlington, it …

WebTherefore, the applications for Darlington pairs have been largely in noncritical circuits not requiring use of feedback. Another limitation is that the minimum voltage drop through the device when conducting must be greater than the base–emitter voltage (about 0.8 V) of the second transistor.

Darlington pairs are often used in the push-pull output stages of the power audio amplifiers that drive most sound systems. In a fully symmetrical push-pull circuit two Darlington pairs are connected as emitter followers driving the output from the positive and negative supply: an NPN Darlington pair connected to the positive rail providing current for positive excursions of the output, and a PNP Darlington pair connected to the negative rail providing current for negative e… cokey crewWebJul 31, 2013 · When the base drive is removed, there is no path to discharge this capacitance of the right transistor, because the reversed-biased base-emitter of the left transistor prevents it. These resistors provide a path for this discharge current.
