  • Rail to rail output stage of an amplifier
    Patent number: 6028481
    Abstract: A gain stage is disclosed for use in an amplifier which provides an output signal. The gain stage includes a first transistor including a base, an emitter and a collector. The base is coupled to an input signal applied to the gain stage, and the emitter is coupled to a first source of operating potential. The gain stage also includes a second transistor including a base, an emitter and a collector. The collector of the second transistor is coupled to the collector of the first transistor for providing the output signal. The emitter of the second transistor is coupled to a second source of operating potential. The gain stage also includes a level shifter coupled to both the input signal and the base of the second transistor. The level shifter provides level shifting and produces a gain signal responsive to the input signal.
