Theory of Operation
Referring to the Simplified Schematic, it can be seen that
the input voltage is applied across the bases of Q1 and Q2
and appears between their emitters. If R
E1-2
is the resist-
ance across these emitters, a differential current equal to
V
IN
/R
E1-2
flows from Q1’s emitter to Q2’s. The second
stage amplifier shown maintains Q1 and Q2 at equal collec-
tor currents by negative feedback to Q4. The emitter cur-
rents of Q3 and Q4 must therefore be unbalanced by an
amount equal to the current flow across R
E1-2
. Defining
