Darlington amplifier
Webby a Darlington transistor, easily switches an ampere or more at 50 V on a time scale measured in milliseconds, as required for actuating a solenoid or a tungsten lamp. Sidney Darlington made at least one other excursion into the world of transistor circuit design. According to Dr. Franklin Blecher, who joined Bell Laboratories around 1952, Sidney WebI decided to make a power DC-amplifier. I used complementary darlington pair TIP142 and TIP147. Also TL082 used for negative feedback. The schematic is as below: I gave 100 kHz sine signal and under …
