FIG. 26 and FIG. 27 show examples of a differential pair amplifier circuit wherein a first emitter of a first transistor is coupled to a collector of a third transistor and to an input terminal of a first amplifier. The first amplifier includes an output terminal which is coupled to a first terminal of a first resistor wherein a second terminal of the first resistor is coupled to a base terminal of the third transistor. A second transistor including an emitter of the second transistor is coupled to an input terminal of a second amplifier wherein the second amplifier includes an output terminal that is coupled to a first terminal of a second resistor and wherein the second resistor includes a second terminal that is coupled to a base terminal of a fourth transistor.
