  • Differential current mode gain stage and methods of using the same
    Publication number: 20020175755
    Abstract: A differential current mode gain stage and methods of using the same are provided. The gain stage may comprise a plurality of transistors. The gain stage is configured to keep at least one transistor of the plurality of transistors out of saturation mode while operating with a supply voltage of less than two base-emitter voltages, receiving an input signal, generating a first output signal if the input signal comprises a common mode signal, and generating a second output signal if the input signal comprises a differential signal, the second output signal having a larger amplitude than the first output signal.
    Type: Application

  • Enhanced slew rate in amplifier circuits
    Patent number: 6456161
    Abstract: An amplifier circuit comprising an input stage capable of receiving and amplifying an input signal, a gain stage electrically coupled to the input stage that is capable of further amplifying the input signal, and an output stage electrically coupled to the gain stage that is capable of charging a capacitance of the amplifier circuit and outputting the amplified input signal. The gain stage of the amplifier circuit comprises a pair of gain transistors with base terminals that are electrically coupled to the input stage, collector terminals that are electrically coupled to a path to ground, and emitter terminals that are electrically coupled to the output stage.
