"WebAug 13, 2024 · Whenever I try anything new as I simulate a differential amplifier, I find I have to adjust a lot of things in the long-tail pair, until I believe it's performing true differential action. (Until I succeed it could be something else like a mixer or adder.) The output needs to make sense since it is supposed to subtract one waveform from the other.

WebProcedure: Differential Amplifier, Long-Tail Pair Impedance is a Resistor. I.1. Find two matched transistors, and construct the circuit above. Of course, all resistances used should be measured and recorded before being used. Make the circuit quiescent (no signal applied) by connecting both bases to ground. I.2. 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.
