  • Multistage differential amplifier with CMFB circuit
    Patent number: 6888407
    Abstract: The invention relates to a multistage differential amplifier having an input stage, at which a differential input voltage is present, a load connected to the input stage, a CMFB circuit and an output stage, at which an amplified differential output voltage is output. In order to improve the stability of a common-mode regulating loop, a current source is provided, which additionally feeds current into the regulating loop and thereby ensures that a control voltage for the load does not fall below a predetermined value.
    Type: Grant
