In a transistor amplifier comprising a pushpull output stage with combined current and voltage feedback therefrom to an earlier stage of the amplifier through a variable attenuator whereby the amount of feedback may be varied but with the feedback so provided that the output impedance of the ...
A large loop negative feedback circuit between the preamplifier stage and a quasi-complementary push-pull output stage is eliminated, and the base electrode of the pre-stage triode is electrically connected to the audio signal input terminal of the audio socket through a fourth capacitor. The ...
Using NPN transistor as Class B Push-Pull Amplifier Amplifiers are used to power up the low power signal to a high power signal. One of the common applications is audio amplifiers such as loudspeakers and headphones. There are four different categories of amplifiers as follows: Class A amplif...

INTEGRATED TRANSISTOR PUSH-PULL AMPLIFIER PURPOSE: To attain the integration of transistors(TRs) by mutually connecting the bases or emitters of respective driver TRs respectively through diodes. CONSTITUTION: The collector of a TR T5 is connected to the base of a pnp type drive... Y Matsutofuer...
A push-pull amplifier, e.g. the double emitter-follower, can also be biased for Class-A operation, so that both transistors conduct over the whole cycle. One transistor's current decreases as the other's increases, but neither transistor's current ever falls to zero. Alternatively, the ...
The pushpull power amplifier has two complementary amplifier stages for the positive and negative half waves. The output transformer (119) has two primary windings each connected in series with one of the two complementary transistor stages (11, 12, 15 etc.). Each of the transistor stages conta...
