press the zero drift, the better the symmetry, the inhibitory effect of zero drift good. But in fact the circuit can not be completely symmetrical, so that the basic differential amplifier circuit for zero drift suppression to be subject to greater restrictions. Change into the way is the basic amplifier circuit emitter resistor connected to a roll, as shown in FIG. Has been able to save two bias resistor Rb12 and Rb22, because a dual DC power supply. Below is a brief description of how it works.
