Apparatus for input amplifier stage |
摘要 |
A differential stage of an amplifier includes an input transistor and a second transistor with a significantly greater emitter cross-sectional area than the input transistor. Quiescent emitter current is divided between the two transistors in substantially the same ratio as the emitter cross-sectional areas so that the emitter current densities are substantially equal.
