摘要：
A classical differential amplifier (100) provides output of unequal magnitude due to its emitter resistance being finite. In order to equalize its output, a voltage follower circuit (200, 300) is associated with each of the inputs of the differential amplifier. The output of each voltage follower circuit is converted to current (202, 302) and subtracted (400, 500) from one of the outputs of the differential amplifier. Subtracting the outputs results in a differential amplifier with both outputs being substantially equal.
