Abstract:

With passage of time, fast and efficient communication with minimum loss of signal is a much-desired aspect in modern technology. Knowledge of increasing demand of smaller, portable and modern forms of technology allows space for consideration of ways to produce devices that are at small size scale and efficient. This research is based on Darlington Transistors because of its rising demand and important features like high current and voltage gain. Proposition of JFET based triple Darlington topology lies in the sector of new researches done to widen the horizon of researchers of the day to help look beyond and capture the next step ahead and predict what next inventions may be. Unlike the conventional Darlington pair, the voltage gain of triple Darlington is considerably high and it also improves the poor response at high frequencies.
