WebTHE DIFFERENTIAL AMPLIFIER. Figure 16 shows — in basic form — how a pair of amplifiers of the basic Figure 11 type can be coupled together to make a “differential” amplifier or “long-tailed pair” that produces an output signal that is proportional to the difference between the two input signals. In this case, Q1 and Q2 share a ... WebDiscrete, resistor-based differential am-plifier with “long-tailed” pair of NPN transistors. Q4 acts as a constant current source re-placing RE to make the outputs more nearly proportional to the input voltage difference. RBIAS sets the current by de-termining the current in Q3 and the cur-rent in Q4 is the same because Q3 and Q4 are matched. north carolina snow meme
